Tire sizes for 17x9

[KcMstang]

Right now the car has 235/45/17 on the front and 245/45/17 in the rear and I'm getting new tires at the end of this week. What is the widest tire I can get on the car without rubbing? The front/rear tires sizes don't have to match this is not a DD only a toy that gets driven on the weekends.

Appreciate the help!

Can I run a 275/40/17 in the rear or stick with the 255/40/17 rear?

Guessing I will stick with the 235/45/17 front.

Alot of factors in play.. but this is 245/45/17 and 275/40/17 w/flipped quads...

I want a tire that will fit without modications. My car is dropped probably 1.5-2" so I was thinking still running 235/45/17 up front with 255/40/17 in the rear.

Na, that's too small. I bought the 275/40/17 on a 2" drop car and they fit fine, no rubbing. Really wish I had got the 295's. Something does rub if there is somebody in the back (adult) but that's not very often and I put really soft springs in the rear that's when it started rubbing.

Flipping your Quad Shocks is hardly a Modification!

Does that matter if I've done a 5 lug conversion? I'm still on the stock 4 lug and I'll look into flipping the quad shocks. I'm getting these tires tomorrow and I might gamble and do the 255/40/17 up front with 275/40/17 in the rear.

sorry if i'm jacking,but i am also wondering the same thing.
what do u have for rim size,off set and back spacing to be able to get 255 up front. do u have any rubbing issues at all? and lastly is ur car lowered?
again i appologize. thanks.

 

[Kumm3]

yes, its lowered, i am running the 03 Cobras, 6.12" backspacking AFAIK.

no TIRE rubbing issues, but at full lock, the inner wheel does hit the A-Arm, but that can be fixed with rack limiters.

I run 17x9, 275/40/17 front and back, no rubbing problems, and quadshocks untouched.

yeah but what year is ur ride. i think the 1990 still had the narrower frontend.

 

[rigamaroles]

I believe his is a 93 gt

245/45/17 on a 17x9 rim will rub up front on a 1988 mustang! If you don't believe me drive to GA and look at my car. Guy at the shop said the rims are too wide for the car.

 

[Blakthorn]

my 87 has 235 on the front and 255 on the rear

The rear required me to flip the quad shocks to avoid rubbing and the fronts rub on full lock.

If I were to redo my choices I wouldve went with a similar tire size all the way around and not a 17x9 wheel, I think 17x8 wouldve been perfect

 

[stangonline]

Depends on backspacing and the car in general. I think you are seeing from this thread that over the years, these cars get modded and there are a lot of factors that determine what tire will fit.

I did a 5-lug conversion using stock (fox) length axles in the rear and sued the 10th anniversary 17x9 wheels with 275-40-17 and they were perfect. I've heard of others with the SN95 axles (wider) with the same wheel/tire combo and they too said that it fit, where I could not see how because mine was so close.
On the front, 275s could touch my fender lips just a little on a real hard bump - so they were a little oversized for the car.

What wheels do you have?

 

[KcMstang]

4 lug Cobra R 17x9...

I'm going to look into a 5lug conversion later on down the road so no worries...

I got 17x9's with 255/40 up front and 275/40 in the back. No major rubbing issues.
