Littler Posted June 28, 2011 Share Posted June 28, 2011 (edited) Hi, looking at getting a TT in the not too distant future and at the minute I'm planning what I want to do and how much it will all cost etc... One thing that I haven't really decided on is the tyres, just wanted peoples opinions on makes, prices and the best place to get them from. The wheels I plan on getting are the Advan RS 18" (in gun metal for those interested) with 9" at the front and 10" inch at the back with an offset of 35, mainly as they get good reviews and look great, plus they fit over UK or upgraded brakes. Through doing a bit of a search on here there are mixed opinions on the widths and profiles to use, so opinions on that are welcome too! From looking round the rears need to be something like 285x30 to be ok for the arches and the fronts need to be something 255x35. Thanks!

merckx Posted June 28, 2011 Share Posted June 28, 2011 I was going to give you my opinion on the tyres for those width wheels to closely match them to the stock dimensions but you really need to take into account of the wheel offset especially if you're going for a 9" wide front wheel.

The offset will be 35 as this allows them to fit without much trouble. Will add that to my first post! Cheers! Quote Link to comment Share on other sites More sharing options...

TTRickeh Posted June 28, 2011 Share Posted June 28, 2011 255/40/18 front, 275/35/18 rear. That's what i'd go for Quote Link to comment Share on other sites More sharing options...
lonbhold75 Posted June 28, 2011 Share Posted June 28, 2011 http://www.kulthea.net/fitment.xls is quite useful too... 255/40/18 front, 275/35/18 rear. When I enter those numbers into the fitment calculator, it states that the front tire height is "Too Tall". Is this actually the case as it seems a fair number of people run this size front tire. I was under the impression you wanted the tire height as close to stock as possible for speedometer/odometer reasons and that front and rear tires also need to be as close to the same height as possible. Maybe I am putting to much faith in the fitment calculator? Just trying to wrap my head around this as I too am looking for tires for the same size wheels only in a 41 offset front and 45 offset rear.

TTRickeh Posted June 28, 2011 Share Posted June 28, 2011 245/40/18 is probably a better size then. You'll easily get 245's on a 9 inch wheel. I had 245's on a 9.5 inch wheel and it didn't look stretched but at 35 profile but there wasn't really enough sidewall for my liking.

Littler Posted June 28, 2011 Author Share Posted June 28, 2011 http://www.kulthea.net/fitment.xls is quite useful too... I have put my figures in and it says the offset is too small for the outside tyre width for front with a size of 255/35 18 with an offset of 35, any thoughts to why as I've seen a few supra's with the same setup and they fit fine?

Littler Posted June 29, 2011 Author Share Posted June 29, 2011 (edited) Think I'm understanding the sizes a bit more now, what are peoples opinions on different tyres makes/models. I get the idea that Pirelli Rosso, Toyo T1R and Bridgestone RE50A are very good road tyres with Toyo R888's being the track choice, what are peoples experiences with these, focusing on road tyres specifically?

dandan Posted June 29, 2011 Share Posted June 29, 2011 255/40/18 front That's what i'd go for You'll struggle to fit that on a 9" with 35 offset. I'd go 245/40/18 or 255/35/18. Quote Link to comment Share on other sites More sharing options...
Westy Posted June 29, 2011 Share Posted June 29, 2011 I'd always try for the deeper sidewall if its possible. Quote Link to comment Share on other sites More sharing options...
Mario Posted June 29, 2011 Share Posted June 29, 2011 It's not unheard of running 315's on 10'' wheels, i'm not saying it's the best, have a read through this thread. http://www.supraforums.com/forum/showthread.php?436740-Max-tire-size-on-10-quot-rim Quote Link to comment Share on other sites More sharing options...
