I am looking to get new tires on my cobra. i have 10.5" wide wheels which have 245's on them. What would be the widest tire size i could get without it looking weird or having to do modifications to my car. Also what would be the best brand of tire for mostly street driving.

There is no way you got 245's on a 10.5 inch rim. I wouldn't put 275's on a 10.5 inch rim. I run 315's on mine.

Most tire manufactures list tire sizes for a range of rim widhts as approved by an organization called The Tire and Rim Association.

Some of the standards are listed below.

245/40R17 8.0 - 9.5
255/40R17 8.5 - 10.0
265/40R17 9.0 - 10.5
275/40R17 9.0 - 11.0

245/40R18 8.0 - 9.5
275/40R18 9.0 - 11.0
295/35R18 10.0 - 12

You can 'cheat' a little bit with little problems. Just wont get max performance.
I have run 275/40R17 on 8" rims for a couple of years even at track events.

Go with 315-35R17's. 245's are streched hardcore on a 9" wheel I dought they went onto a 10.5".

You can easily stretch a 245 over a 10.5" wheel. I have done it before on a standard tire change machine with little issues at all. I don't recommend it as it exceeds the recommended width by 1.5". I have done a 195 over a 9" wheel before for a VW guy. They are stretched pretty good, but no issues at all. I have never had an issue with a stretched tire rolling of the rim during hard corning, but you do run the risk of making contact with the wheel which will cause damage.

A 275 on a 10.5" wheel works just fine. 275's are rated to fit up to 11" wheels with no problems. Of course they don't look as good as a 315/35. You can also go with a 285/40 which are just about 1/4" different in over all diameter and 1.4" in tread width between a 285 and a 315.

Just because you can do it, doesn't mean it is safe. I would love pictures of a 245 on a 10.5" rim

I agree that just because they fit, doesn't mean that they are safe. I was just making the point that they do fit. I personally would stick with what the tire manufacturer suggests.
