a98pmalcolm Posted August 24, 2011 Share Posted August 24, 2011 (edited) Ok. I think I'm settled on the BK993 Wheels Will 19" x 8 ET42 for the front and 19 x 9.5 ET45 for the rears 114mm Stud Diameter be ok? If so what tyres size will I need? ATM I have 235-45-17 fronts and 265-40-17 at the rears. ET35 F&R I like the width my 17" wheels but with 19" wheels they will need to be a lower profile and I don't really understand working out what profile with a thicker tyre on the rear will work out with a thinner tyre at the front to make it look even. Advice please So I can get them ordered http://img233.imageshack.us/img233/4230/phpthumbgeneratedthumbnk.jpg Edited August 28, 2011 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...

Dnk Posted August 24, 2011 Share Posted August 24, 2011 I've posted a tyre size fitting chart quite a few times now but once more wont hurt Wheel and Tyre sizes Here is a usefull guide along with a tyre calculator You should use the tyre calculator to get the correct profile to keep the rolling radius as close to o/e as possible. http://www.etyres.co.uk/tyre-size-calculator.htm 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 Quote Link to comment Share on other sites More sharing options...

Tyson Posted August 24, 2011 Share Posted August 24, 2011 you want 255/30/19 which will be exactly the same RR on the rear and 235/35/19 on the front which will + 0.6% Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted August 24, 2011 Author Share Posted August 24, 2011 Thanks DNK.. The tyre sizes will fit nicely Now how about these offsets? How do they sound? Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted August 24, 2011 Author Share Posted August 24, 2011 you want 255/30/19 which will be exactly the same RR on the rear and 235/35/19 on the front which will + 0.6% That's the exact size for the front I was looking at. I was more on the idea of 265/30/19 on the rear. That should be ok shouldn't it? And then its the exact same profile look as the front http://img200.imageshack.us/img200/4346/unledqf.jpg Quote Link to comment Share on other sites More sharing options...
Tyson Posted August 24, 2011 Share Posted August 24, 2011 Thanks DNK.. The tyre sizes will fit nicely Now how about these offsets? How do they sound? They are pretty much stock offset, they are the same width and virtually the same height so I can't see there being a problem. Ripped fear what tyre size, wheel size and offset combo are your running Same as listed above? Quote Link to comment Share on other sites More sharing options...

Tyson Posted August 24, 2011 Share Posted August 24, 2011 (edited) 265 on the rear will make it 1% out and you haven't changed the profile just the width. Just looked at the picture and your doing it wrong, its not front and rear tyre its stock tyre vs new tyre.

a98pmalcolm Posted August 24, 2011 Author Share Posted August 24, 2011 ok re did it, Its not to far off, so aslong as the offset of ET42 fronts and ET45 rears are all good, all should be well: Does this look correct? These are compaired with the tyres I have now. http://img853.imageshack.us/img853/5803/frontsgr.jpg And Rears: http://img32.imageshack.us/img32/2029/rears.jpg Quote Link to comment Share on other sites More sharing options...
Tyson Posted August 25, 2011 Share Posted August 25, 2011 yep that looks good but the stock rear width is 255 not 265. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted August 25, 2011 Author Share Posted August 25, 2011 Ok im keen on 265 for the extra grip as that's what i have now. My main concern in the offset. I spoke to Wheel Worx today and thet said ET42 on the fronts wont clear the front brakes on a supra. I will need ET30. Is this correct? Many thanks for all the help.
