What size of tire should I run on a 93 LX which is lowered atleast 1 1/2" and I will be using a set of 95 style 17x9" rims with 6" backspacing. I was looking at 245/40/17 tires.
I've got 255/55/17's on 9" wheels all the way around on my 86. I had to trim a little off of the lower fender extension on the front of the fender to make them clear but, other than that, no problems. There isn't enough room for crimp on wheel weights tho. Had to go with stick on's.

I use 285/35 in rear but have not lowered yet. I think you can only use 275 on back if lowered. As far as the front I use the 235/40 tires so that if I do rub its the rim and not the tire.
I am thinking about 235/40/17 front and 255/40 or 275/40 rear. On my 97 GT I had 17x10.5 03 Cobra rims with 285/40/17 and had to remove the quad shock. I don't want to do this if I don't have to. Will the 275/40 fit without any mods? If I need to the car will be raised back up a little.
I have the same wheels on my 88. I have 245/45/17 all around. But when the rear tires get worn out I am going to go with the 275/40/17's.
I have also lowered the car. The front rubs a little at full turn but not too much.

ya i was wondering about this too, i have a 91 gt completly stock, and i have a set of 17x9 cobra rims with a +18 offset i know i can fit, the 245s but can i fit the 275s out back with no problems? thanks for the help
The wheel sizes helped, but what about B.spacing and offset ? I am looking at a set of 215/40/17 tires on rims that have a 5.5 b.spacing and a negative offset. Will they work on a 1989 fox? She's lowered about an inch .
what tire size for 17x9" Cobra rims
