Justin Posted December 14, 2003 Share Posted December 14, 2003 If stock is: Front - 235x45x17 Rear - 255x40x17 What should the sizes be for 18" wheels please folks? Ta Justin. Link to comment Share on other sites More sharing options...
Terminator Posted December 14, 2003 Share Posted December 14, 2003 To maintain speedo accuracy, if your car left the factory on 17’s the rears should be 255 35 18. but 265 35 18 , 275 30 18 and 285 30 18 are common choices. Fronts 235 40 18 or 245 40 18 If your car started life with 16’s then 275 35 18 are best for speed accuracy followed closely followed by 285 35 18, same choice of fronts as above.

roscodav Posted December 15, 2003 Share Posted December 15, 2003 what if you are thinking of venturing into the world of 19" bone shakers? (i have little 16s atm....i know i know!) Link to comment Share on other sites More sharing options...
Terminator Posted December 15, 2003 Share Posted December 15, 2003 For 19's, 275 30 19 and 285 30 19 are close to the same circumference as stock 16's for the rears. 295 35 19 are next best width without arch work??? Link to comment Share on other sites More sharing options...
Justin Posted December 15, 2003 Author Share Posted December 15, 2003 Thanks Phil nice one, I think my car started life with 17's as it is a 93/94 GZ and the sticker inside the door makes references to 17's. Link to comment Share on other sites More sharing options...

Ah..... no it didn't. Just looked at the sticker again and it started life with 16's. Will go for your other recommendation instead. Link to comment Share on other sites More sharing options...
Terminator Posted December 23, 2003 Share Posted December 23, 2003 I did not realise Areotops came out on 16's. Link to comment Share on other sites More sharing options...
Supragal Posted December 24, 2003 Share Posted December 24, 2003 Who cares what it started life on?! Get some proper bling on there!!!!! Link to comment Share on other sites More sharing options...
Terminator Posted December 24, 2003 Share Posted December 24, 2003 Supragal is right Justin, you too can turn your car in to a paper weight, stick some 345 25 18's on, still speedo accurate too. If you really want to spread your rear you could get some 16's and go for 445 25 16 only 0.2mph out at 60. You may need a kit wider than Supragal’s to fit them in though:p Link to comment Share on other sites More sharing options...
Supragal Posted December 24, 2003 Share Posted December 24, 2003 Speedos can be re-calibrated 335/18/35's are the way forward Link to comment Share on other sites More sharing options...
Ian C Posted December 24, 2003 Share Posted December 24, 2003 We need a smiley face with something going over it's head Methinks Termie meant that your speedo is still accurate as it reads 0 at 0mph :D Notice how you get abuse in loads of threads as soon as no-one has anything to do? -Ian Link to comment Share on other sites More sharing options...
Darren Posted December 24, 2003 Share Posted December 24, 2003 Originally posted by Terminator For 19's, 275 30 19 and 285 30 19 are close to the same circumference as stock 16's for the rears. 295 35 19 are next best width without arch work??? So can I have some confirmation do 285's and 295's both fit ok on the back of a Sup? Ive gotta get some new tires that all... Thanks.. Link to comment Share on other sites More sharing options...
Nick Posted December 24, 2003 Share Posted December 24, 2003 There's a wheel upgrade calculator on the web somewhere, can't remember the link though, sorry... FYI I have 275/35ZR18 and 245/40/ZR18 and at the time was told these would give the closest rolling radius to stock for an upgraded wheel/tyre combo.

Cheers Nick, I'm gonna be running 19's and want to know how wide I can go on the rears without rubbin the arches? And am I going to get more grip from say 285/295 over 275 etc...?

Nick Posted December 25, 2003 Share Posted December 25, 2003 Darren, This is a good page, gives a lot of info and you can calculate which rim/combo will give you the same rolling radius as stock. Whether they'll rub on the arches though I don't know, sure there's someone on the board with 19's..... http://www.chris-longhurst.com/carbibles/index.html?menu.html&tyre_bible.html Link to comment Share on other sites More sharing options...
