Tire size question.

[Rlugo87]

Hi guys,

I got some new wheels for my 01 gt. They are on the car right now with 2 new goodyear g force sport 245/45/18's up front and rear. Now the rears are shot so i happen to have 2 brand new 245/50/18's in the same g force sports that iv had sitting in storage since last year. Will these fit in the rear without rubbing the strut? The 245/45/18's in the rear only have about a half inch or a bit more clearance from the strut. Im ok with the rear tire being .96 inch taller than the front as this will fill the larger ammount of wheel gap i have in the rear after my drop springs got put in. Thanks guys.

It's over 3% different and I would not do it.

Very possible it will toss the ABS light because of the difference in wheel speed. Just sell those two tires and buy 2 tires that are the right size.

A 245/45-18 tire is the same width as a 245/50-18 tire.
Hence the 245 designation.
The only difference is the sidewall height. 45 vs. 50.
