Al Massey Posted January 28, 2009 Share Posted January 28, 2009 Ive been searching all day and my brain has melted:blink: Im more confussed now than i was when i started. If i was to fit 18" x 10" alloys with an offset of 40 to the rear of the supra, would it fit or would i need to do some arch work? bearing in mind i do plan to have overfenders fitted at some point. Now i know that the original offset is 50 and staying close to it is best, and that you can go +/- a bit. So Does an offset of 40 makes it stick out 10mm further? Also what would be the best width tyres to fit? 265, 275, or 285?(now this is what confuses me the most as i dont understand how it all works) Cheers for any help in this allan:) Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 28, 2009 Share Posted January 28, 2009 You mention arch work but the wheel size is sensible... I'm conflicted whether to boot this out to chat or not. Hmmm. For now it stays -Ian Quote Link to comment Share on other sites More sharing options...
merckx Posted January 28, 2009 Share Posted January 28, 2009 (edited) Does an offset of 40 makes it stick out 10mm further? Yes, but a 10" wheel is also going to stick out a further 1/4" (6.4mm) over a stock rear 9.5" wheel . So overall 16.4 mm further out than a stock rear wheel. Stock rear tyre on a TT is 255/45 17 , tyre dia= 661 mm Best rear tyre for a 18" rear wheel is 255/40 18,... dia=661 mm Edit, I'm not sure if a 255 is a little narrow for a 10" wheel, even if it is a good diameter You could go wider if you wanted too. Use this fitment tool to compare a stock tyre/ wheel with aftermarket sizes. http://www.etyres.co.uk/tyre-size-calculator.htm Edited January 28, 2009 by merckx (see edit history) Quote Link to comment Share on other sites More sharing options...

Now im more confussed as there is two different answers. i mentioned arch work as ive read it a few times while doing the search and that the wheel will pertude further so hence the question about arch work, will it need doing?

dr_jekyll Posted January 28, 2009 Share Posted January 28, 2009 i use 10 rears with 265/40/18 on a +35 i think , and thers is no rubing unless i go over a bump hard and it just about toches the tyre nothing that bothers me though, im on stock n/a rear suspension Quote Link to comment Share on other sites More sharing options...

For now it stays -Ian So what are the key points you look for in a thread when deciding where of the two sections it should dwell? Just so I am clued in in future! This is not a hijack! Just a query to benefit us all. Right!! Quote Link to comment Share on other sites More sharing options...
merckx Posted January 28, 2009 Share Posted January 28, 2009 (edited) Now im more confussed as there is two different answers. I didn't say it wouldn't fit, a 10" wheel with a 40mm offset is a good size for the rear. bearing in mind i do plan to have overfenders fitted at some point. With this in mind you'll want the wheels/tyres to stick out a fair bit.
