I have got an offer to buy four brand new Bridgestone Potenzas at a very good price. Rears are right size 18" 275X40 but the front tires are 18" 225X45 when they should be 215X45, do you think its ok. The car is a 360.
The oversized front tires will certainly tear your front fender edges up. You need to stick with stock sizes. I have personally seen a 360 take damage due to the wrong front tires.
Even from going wider on the front by ONE size/width?? How wide were the tyres on that 360 to have caused damage to the front gaurds? Going one size wider on the fronts would seem fine to me. But I dont own a 360, so I wouldnt know. One would assume 10mm wider tyre would still have clearance under the gaurds on the 360.
Especially when the suspension is at stock height. Yes, I'd agree with you as well. If it has been lowered, then it's a completely different ballgame.
People have complained about standard tires on stock ride height catching the front fender lip when turning full lock. Fender rolling is the answer. Russell
I have damaged my lh fender with original size tyres, splitting the lip. It is a very common problem. I also have those tyres on SA02A??(still sold in this part of the world), the replacement equal in US is called something else I think. They are ok but I get the ASR light coming on under hard acceleration a lot more than the P Zeros( but they were 2x the price).
Not true. The 255 will mess your fender. Im running with 245 at front with 19" wheels and it just fine. Try it and you will be just fine.
Thanks guys!! Now, this is interesting! Stock tyres rub on the front guards with 215 and you are running 245s and dont have a problem? Perhaps your offset is a little different to the stock wheel David?
+1 I have 255/30/19 on my 360 no issues, now I am not slammed like others but the car is lowered. I have no clearence issues at all. Good luck.
Assuming fender clearance is ok, the other issue would be changing the stagger. 360s are already a bit tail happy (compared to 430s), so going to a larger front size while keeping the rears the same will aggravate oversteering tendencies.
I'm assuming the people chiming in with oversize tires in front with no issues have aftermarket wheels with a different offset. I owned a 360 and now an F430, and my 360 had stock wheels (starfish), and stock width in front. My tires still caused some minor bending of the inner fender lip with a complete stock factory set up. My Ferrari dealer said it's an inherent issue with the 360 model.
NF1s and NF2s are 9" F and 12.5" R compared to 7.5" F and 10" R OEM. I have NF2s on my 575M and they are very, very wide, especially in the rear, but work fine on 360s (and 575Ms). The difference in height and width on a 225/45 vs a 215/45 tire is small for a tire, 25.97" vs 25.62", and only half that difference (0.18") is sitting above the wheel center line. 10 mm width difference is only 0.40", half of which is on either side of the wheel, or 0.20". For a stock ride height car, that will not make much of a difference unless you are at full lock going over big bumps. So you have about 1/5" more rubber in two directions. Taz Terry Phillips
