Kaan W Posted February 13, 2013 Share Posted February 13, 2013 Can someone please work out for me if these tyres will fit. Basically the setup at the moment is 315/30r18 on a 12j et20 wheel with 20mm spacers. Im looking at getting a 345/30r18 tyre and running a smaller spacer or no spacer. The current wheel and tyre combo fits fine without the spacer but they are needed to fill the arch, unless of course a wider tyre is fitted. I just want a definate answer from someone that can calculate for me with the information given. Thanks! Quote Link to comment Share on other sites More sharing options...

Justin Bieber Posted February 13, 2013 Share Posted February 13, 2013 Did you say somewhere that your current tyres scrub under acceleration? because a 345/30 will be taller and will rub even more Quote Link to comment Share on other sites More sharing options...
Kaan W Posted February 13, 2013 Author Share Posted February 13, 2013 (edited) 345 tyre! Yeah theyre drag radials I saw a supra on another forum looks the nuts. Did you say somewhere that your current tyres scrub under acceleration? because a 345/30 will be taller and will rub even more Yeah they did but ive lifted it up now. Pointless having it that low when the exhaust, bumpers and arches scrape everything. Using a tyre diameter calculator they will increase the diameter by 18mm which will be fine. Im just confused whether they will fit or not without spacers or a smaller spacer.

Kaan W Posted February 13, 2013 Author Share Posted February 13, 2013 345 should be fitted onto a 13" wheel not a 12" A 11.5" - 13" rim Is what they will fit according to online calculators and the companys that sell them. Quote Link to comment Share on other sites More sharing options...
