wheels too big?

[Guest SupraGTE]

this is my 20" with 25 profile yokohama 285 , 18 is sooo the 70s LOL ,no it is wath you like, yes it is not the most comfortable to drive but .... but so do rock hard coilovers, steel diff etc etc , it is just what you self like

 

 

i have a spare set of 18 and 19 just incase

20's aren't b-road wheels I don't care how "well setup" the suspension is

[Guest SupraGTE]

i would not use 20" if i had to use my car every day

then i would go for 18 , thats my opinion but i would also throw my Kaaz diff away if i had to use the car all days:)

[Scott]

heres one with 20s looks to chavvy and the ride will be shite

Those could be 15's and they would still look shite lol.

And just what attention should i be paying pray tell?

 

you shouldnt be paying attention to it , the guy that asked the question should, as i my opinion its a correct statement

Tricky-Ricky - Just to clarify this, as it seems easy to misread it, but Dr Jekyll was suggesting the person who started the thread should pay close attention to your post.

I don't think he was taking the p1ss bud, he was saying backing up what you said

I know people think 20"s is crap ride but they talking out of an urban myth. If you have a proper setup 20"s will corner a lot better than 18"s. I've tried both and ride is awesome with 20"s, profile is 30 and grip is amazing too, I use car as everyday run around. Then again where people go wrong is they buy crap quality wheels without proper setup. You have to spend some serious money to get a good ride no matter the "s. You can get cheap shitty 16"s and it will ride like an escort. Skyline and all new supercars go for bigger alloys but they are expensive and the setup around them is well thought as well. Off course they not designed for drag race but who cares? Get a spare set of alloys. It's down to personal taste and how much you willing to spend, if you just want any 20"s then don't do it, go for smaller

 

just my opinion

[jevansio]

"If you have a proper setup 20"s will corner a lot better than 18"s. I've tried both and ride is awesome with 20"s, profile is 30 and grip is amazing too"

 

You are talking out of your urban myth there . Lower profile tyres will have less grip than a higher profile under bumpy conditions, the 20 will leave contact with the road whereas the 18's higher wall will be able to absorb the bump

 

How much do each of your wheels weight?

 

Oh this is a sad story

 

As soon as I got them in they were rubbing like bitches so we raised the tein up a bit. I had rolled out the arches previously but it didn't seem to help at all!

 

So next day I went to a place where this guy re-rolled and tried to pull out the arches without damaging the paintwork. It did help a lot, it rubs a little bit now sometimes but not to an extent where it does any damage to the tyre. Plan is to fit the overfenders so that it will clear 100%

Have you got overfenders fitted yet & do the 20's still rub

I'm afraid would only be prepared to believe this if you where to run two Supras with full set up for each size wheel on a track and prove the lap times, otherwise as i said common sense says it wont happen;)

 

And as i said before the Supra was NOT designed for large wheels therefore the suspension geometry is not designed to accommodate them, unlike some supercars that where designed to have 19" or 20" wheels.

[Scott]

The same argument can be said for anything over 16" as that is what the chassis was designed for.

 

How many people, honestly, would be in danger by running 20" wheels? Very few of the folks on this forum run their car hard enough to have to worry about it. The problem with the lower profiles isn't losing the traction, its getting it back once it breaks. The bigger the profile the easier it is to catch. You can lose traction with any profile, granted 20" will give a bit easier.... I can't see anyone driving on those limits on our roads though.

 

People who want to track their car will have suitable 17" wheels. Saying 18's are ok because you have 18's and think they are fine is not a substantial argument. Anything over 16" is wrong in any basis of this argument.

 

FWIW I have 19's and I haven't crashed yet. Lets have a look at the people that have damaged their car on the forum over even the last 6 months and see what size wheels they are running.

See this road:

 

 

This is an example of the types of road round my area that I like to take the Supra. You can see how uneven it is by looking up it. I will put hard cash on a 18" wheel having an easier time putting the power down than a 20". The reason I say this is I found it much easier putting 600bhp down up there on 18's than 19's, the 19's felt sooooo twitchy, like it wanted to break traction at every bump, the 18's felt much more confident

 

Another shot:

 

 

There are loads roads round mine where I can have all 4 wheels off the floor easy, 20's won't cut it round here

 

Funnily enough you can see in that last shot the eneven road surface warning sign

Did you crash due to driving with 19's on? Would you have crashed if you had 20's on? Would it be even better with similarly light 16's on?

 

Jay, FWIW I am with you on what you say. My point is that people jump on too many band wagons. Yes light 18's with the geo setup properly will handle better than heavier 19's with the geo not properly setup (this was the case with you IIRC?). If you setup the car on an even par with similar wheels all be it different sizes there may be a SLIGHT difference on how the car handles. Its all about the rubber on the road at the end of the day.

 

My point is that 20's isn't going to make the difference that people make it out to be. The difference from 18's to 20's is going to be the same as 16's to 18's. It will be there, but won't be dangerous.

 

Solid fact, people want bigger alloys than the stock ones. Everyone says 18's are OK because they prefer them, not because of any justifiable evidence that they are any good. You feel a massive difference. Take a shite set of 18's that weigh 12kg and tell me the car handles just as well on that road. Is it down to the diameter of the wheel?

I know bud (yeah I went from 12.5kg 19's to 10.5kg 18's)

Nobody is saying it is dangerous, they're saying it just isn't as good

Funny you should say that, my old wheels 19 12.5kg felt pretty crap TBH, I drove Ro's car (18 12.5kg Ultralites) ages ago and both myself, Ro, & Michel said his car felt loads better than mine (at the time we didn't know the weight of the 18's).

 

I sold Ro my Racing Harts and took his Ultralites to sit my car on until my wheels turned up (which is when I weighed them & found them to be the same weight as the 19 RH's). Was talking to Ro & he said the 19's didn't feel as planted as the 18's, that is a direct 18 to 19 (12kg to 12kg) comparison. I didn't drive my car with the 18's so can't comment, just chucking this info out there

My comments aren't directed at you though mate, it's the a-typical bandwagon jumpers I am on about. Have a look through the comments and you will see what I mean. I have heard 20's being likened to death dealers on this forum.

 

I know there will be a difference, I agree that it may even be noticeable when pushing it. It won't cause death though, it will cause ever so slightly slower cornering, a bit more tram lining, harsher road feel and some more road noise. Exactly the same as what happens when going from 16's to 18's.

 

In your case 18's are a preference. They are the right compromise, for you, between looks and functionality. You could go with 20's if you prefered the looks but you would know that there would be a slight compromise in the handling and chuckability of the car. You have taken the compromise from stock size wheels to have the aggressive larger wheel look.

 

This is all this guy is asking for. He is not looking to be told a lot crap about how his car will be undriveable with 20's on.

 

I would love to set a challenge. Anyone on this forum in your car (as an example) with your 18's on vs the stig in your car with 20's on. I know who my money would be on.

 

The stig would get round a track faster on the 18's over the 20's but i'm pretty sure he would still make it round in one piece

I know bud, totally understand where you're coming from

[Guigsy]

people seem to be forgetting 20's look utterly rediculous on a supra.

[jevansio]

I only have 1 question, 16 to 20", what gives, side wall or rolling radius, if it's side wall you're losing 2" of give, don't tell me that won't be felt, if it's rolling diameter, every mm will make your car accellerate slower, my 18's have the same rolling radius as stock & I'm happy the 1 inch reduction in sidewall, can any 20" rim guys say the same?

 

In fairness my car came with 17's so change the above to 0.5 inch reduction in sidewall for me vs 1.5"

Edited November 22, 2009 by jevansio (see edit history)

[Scott]

With 20's I don't think you can give up enough sidewall to be honest. I think the rolling radius has to come into play (my first comment was on this IIRC).

 

20's is too much for me on a Supra. Too much of a compromise. In fact, I wish I had gone with the 18" wheels now as they look pretty much identical (more to do with saving £500 though, rather than the handling lol)

[Scott]

They can look good. Takes the right wheel with the right kit. The example given earlier with the ebay sup is not a fair compromise. Those wheels in 16" form would look ridiculous.

Believe it or not I have always been in agreement with your opinion, as it is the same as mine. That is not to say a larger compromise can't be taken to accomodate 20's though. It just isn't for me, it's too much.

 

The guy asked what are the drawbacks of 20's. I think I gave the drawback's fairly rather than just saying the car will handle like shit. It won't handle like shit, there will be a compromise. As always with a larger wheel. The further from the norm you go, the more of a compromise you have to make.

[jevansio]

I have one more drawback, when I was running 19's I hit a series of potholes, they affected both sides of the car (imagine 5 holes arranged 2 x 5), both front tyres were running a lower profile than the rears, both sides of the car passed over exactly the same holes, front to rear weight dist was as close to 50/50 as any Supra is, both front wheels suffered rim damage, both rears never

 

To add values to the above, fronts were 235/35 rears 295/30, wall height will be 82 & 88 respectively, 6mm was the difference between buckling a rim and not
