Luxluc Posted August 20, 2014 Share Posted August 20, 2014 18" suit the Supra the best mate Quote Link to comment Share on other sites More sharing options...
Dnk Posted August 20, 2014 Share Posted August 20, 2014 (edited) 18" with a higher profile tyre will help the harsh ride, what are your rim sizes also what suspension do you have ? Use online tyre calculators to get the correct tyre sizes http://www.etyres.co.uk/tyre-size-calculator.htm http://www.1010tires.com/wheeloffsetcalculator.asp Rim width---Min tyre width----Ideal tyre width-------Max tyre width 7.0 inches-----195 mm--------205 or 215 mm-----------225 mm 7.5 inches-----205 mm--------215 or 225 mm-----------235 mm 8.0 inches-----215 mm--------225 or 235 mm-----------245 mm 8.5 inches-----225 mm--------235 or 245 mm-----------255 mm 9,0 inches-----235 mm--------245 or 255 mm-----------265 mm 9.5 inches-----245 mm--------255 or 265 mm-----------275 mm 10.0 inches----255 mm--------265 or 275 mm-----------285 mm 10.5 inches----265 mm--------275 or 285 mm-----------295 mm 11.0 inches----275 mm--------285 or 295 mm-----------305 mm 11.5 inches----285 mm--------295 or 305 mm-----------315 mm 12.0 inches----295 mm--------305 or 315 mm-----------325 mm 12.5 inches----305 mm--------315 or 325 mm-----------335 mm Edited August 20, 2014 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Bally Posted August 20, 2014 Author Share Posted August 20, 2014 Think suspension is standard jap spec but the tyres that are on look like rubber bands think there 35s gonna go for 18" 50 high should smooth it out Quote Link to comment Share on other sites More sharing options...
Abz Posted August 20, 2014 Share Posted August 20, 2014 Yep, agreed on 18's being the best compromise between looks and ride quality. Follow Dunk's chart, mine feels lovely and my wife has never complained that the suspension feels rough or hard. Especially considering she drives the Supra a fair bit too.

Dnk Posted August 20, 2014 Share Posted August 20, 2014 (edited) What width are your wheels ? If they are stock width on the rear (9.5") and you fit a 255 50 18 tyre it will be 76 mm or 3" bigger in diameter than stock which is not a good idea. Any wider than 255 with a 50 profile and that figure will just get seriously worse I doubt there are many if any 18 tyres above 255 in width that you can get with a 50 profile Edited August 20, 2014 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
