I have searched and am not sure I found what is the widest tire I can fit on my '97? Tirerack shows for 17" wheels the optional fronts are 255/45-17 and back is 275/40/17, and with 18" rims shows 245/40-18 on front and 285/35-18 on back.

Therefore, I wonder if '03 stock tires (275/40-17) can fit all around?

Thanks for any help!

Just put on the 10.5" X 17" with the 275/40 without spacers on the back of my 97 (stayed with the 9" on front) there isn't enough room for my pinky finger, now between the tire and the bracing. You can get spacers to shim out for 11" rims if you need the .5" extra. Photo in the pics & vid forum.

That's a great picture! Are those 275's on front as well? So, without spacers 275-40/17's should fit all corners, mostly I am concerned about the front end?

The fronts are the original 17"X9" rim size and tire 245/45. Did that to not effect the front geometery.

I have 10.5 x 17, 1998 Cobra rims on the back of my 96 with P315-35-17 Nitto drag radials, and the front is P245-45-17. The fat tires look good on the back with no clearance problems. The tread life on those tires is only 15,000 miles or so.

The 315's fit on back with no problems? Wow...that's what I would like to have...but I'll settle for the 265's I have now.

However, I still don't see anyone with 275's up front...I am thinking about buying a friends '03 wheels and tires and all 4 are 275's, so I am concerned about fitment in the front...

Yes, the 315's fit with no problem on the back. I would post a picture from underneath but I will have to figure out how to post photos. I went to Big O the other day and they say that a 275 will fit in the front on the 9" rim, and that's the widest tire that can go on the front. Good luck.

I've saw a few guys who autocross with 275/40 17's all the way around.

HOW TO POST A PICTURE

The easiest method is to use a hosting site like www.tinypic.com (http://www.tinypic.com) (for one photo) or www.photobucket.com (http://www.photobucket.com) (for multiple photos) - free, simple, fast, and tinypic doesn't even require registration. They both automatically resize your pic. Just follow these simple steps...
1- Know in advance where the file that you wish to post is located. (to make it easier, copy the file to your deshtop)
2- Go to the hosting website you chose and use the 'browse' button to locate the file on your computer. Click on the file.
3- Click the 'host it' or 'submit' button.
4- Several different formats will be generated in the lower window; choose the IMG format and copy that entire link into your post. (NOTE: You may only see the link until you click 'preview post', then you'll see the pic.)
5- Click submit and you post is complete.

Try it, you'll like it!

A 17x9'' wheel will fit all the way around without any issues. You can fit a nitto 315/35/17 drag radial on that wheel for the rear without issues as well. The 17x10.5 wheels with 315/35's take a little work. What you will need to do is unbolt the quad shocks back there and flip them over. This will work best. Or, if you have aftemarket upper and lower control arms, you can just remove the quad shocks all together. Also, I've seen some cars with 17x10.5 wheels that rub the exhaust pipe on the passenger side. So some adjustment there is required in some cases. Or, you can just pick up a set of 1/4'' spacers for the rear. My car required no modifications other than a quad shock flip (I removed mine actually) and it works like a champ.

Thanks, Josh...that's good to know! How do you like the ride on the 315's?

I don't notice a difference in the ride with the big tires back there.

BTW, how's the fitment of a 315 on a 9" wide wheel? Any concerns during hard cornering?

I'm not a big corner carver so I'm not sure if you'd have any issues or not.

Thanks for any help![/QUOTE]

Back to the original question, I do use Nitto 275/40-17 road race tires all around. They are mounted on 17x9 rims with 5.98" backspacing. Except for a very rough transistion from the oval to the infield road course at Nashville Superspeedway, which caused a hole in the right inner fender, I have not experienced any fitment problems. My car sits about 1" lower than stock with more negative camber and positive caster. 2003 Cobra wheels have a 6.12" backspacing which may cause some tire rub issues at extreme lock postitions of the steering wheel. 2003 Cobra lower control arms are different to eliminate this problem.

When driving on the street with my above wheel/tire combination, the car wants to follow any imperfection in the pavement. Since the 2003 Cobra Goodyear f1's do not have as aggressive tread blocks as the Nitto's this may not be a problem.
