I'm looking for wider than stock tires for 15 wheels as the title says. I would like 225's, if they fit in the wheel-well. I am currently on stock suspension, but am going to get a drop in the future, hopefully sooner than later. The tires would be for 15x7 OZ Ultraleggeras.
I found 225/45/15, but am slightly worried that the decreased sidewall height would look goofy, especially at stock ride height. I have only found summer tires in this size though.
At 225/50/15 (pretty close to stock diameter) there is only Kumho AST's and some summer Toyos.
How low of temperature will Summer tires work before it's bad to use them?
Summer tires start getting noticeably harder at 50 degrees or so. At 40 degrees they can loose traction fairly easily on dry pavement (acceleration and especially braking). Below freezing they're very hard and very slick. Preventing tire lock up under heavy braking becomes a serious concern/challenge. Traction in wet conditions (not even considering ice or snow effects) is almost non existent when the tread compounds get that hard.
a 225 tire on a 42mm offset wheel may rub the fender a little.
I used to autox on 225 tires on a 15x7 45mm offset wheel and got a little rub. not bad, but enough to take the paint off the inner lip. and your tires would stick out 3mm more.
Thanks Gentlemen. So since the 225/45/15 (23.0 in dia) are a shorter height tire than the stock 195/60/15 (24.2 in dia), would that prevent (or at least decrease) the rubbing mentioned even though they would be on a 42mm offset wheel?
I have 912's on my Miata and really like them on dry pavement (ok in the rain). They have a slighty softer sidewall than the 512's but still offer good lateral grip, predicable breakaway, excellent stopping and decent ride quality. They are, however, terrible on ice and snow and are truly a three season tire, not an all season one. The 912's wear better than the 512's.
