Tire size

[Ticky_3v]

I found the wheels I would like to go with they are deep dish cobra reps in the rear and non deep dish in the front.The fronts are 18x9 and the rears only come in 17x9 and 17x10.5, I was wondering if you guys had any tire setup recommendations to keep rears meaty I want I to look similar to this.

All help greatly appreciated

My son has a ‘99 GT with 17x9 front and 17x10.5 on the rear. Tire size is 275/40/17 and 315/35/17 which you could run, but they are about 1.5” smaller in diameter. Also, the Cobra reps are probably meant for an SN95 with lower offsets.

If you run 18’s in the front, tire diameter will probably be larger than the rear

305/45-17

To run wider tires that are close to the stock diameter, you'll need any of the following sizes:

255/50R17 or 265/50R17
285/45R17
315/40R17

255/45R18 or 265/45R18
285/40R18 or 295/40R18

255/40R19 or 265/40R19
295/35R19

Genuinely trying not to come off as an a-hole here...
These cars will easily fit a 315 inside the fender. You don't need the rears poking out 70s custom van style to look meaty.

I think 305/45R17 is the size you’re looking for

This is a 305/45 but on an 18" rim. You would have another 1/2" gap with the fender. This is Lowered on I believe I ran the ProKit springs back then. But a nice tall sidewall is what your looking for if you want to fill the wheel well.
