i have 05 supercrew with oem wheels and 2 1/2"autospring leveling kit. would like to have bigger tires than the 255/70r17's that came on it . any help would be appreciated.

 

You can fit 33s.. and if you are 4x4 you can fit 35s.. Problem with 35s is the stock wheels are very skinny.. Good luck. If I we're you I'd get some 33" BFG Mud Terrains!

 

I tried 35/12.50 17 yesterday on my stock rims cleared easily till turning. When in a sharp turn hits upper a arm.I guess my question would be would a 33/12.50 17 work. I don't know if the cooper st tire is just to wide for my stock rim?

 

It probably won't work the only way to really figure it out is to try it, cause the stock wheels are like 9.5 wide..

 

I believe that the stock wheels are actually 7.5 inches wide.

Then there is really NO WAY in hell they will work..

 

from cooper's site:
33X12.50R17LT 114 Q D OWL 8.50 - 11.00 10.00 12.36 32.63 9.80 2600 20.0

thats your approved rim width for the ST's the stock rim is 7.5" youd probably be fine running that tire on your stock rim.

hell, im running 33x12.5r18 muds which are rated 9" minimum on my 7.5" rims- offroad with no problems-

i say go for it dude

 

appreciate all the feed back will try the 33/12.50 17 out to see if they will work. thanks for the response.jt

 

I'm running 305/70/17 and it recomends atleast a 9.0 inch rim and I'm using the stock rims and having no problems at all. The tread will probably wear a little faster in the middle on mine but so far they haven't. If you go with the coopers you shouldnt have that much of a problem.

 

proffessor thanks for the information. just really glad i found out about this sight for all the questions i'm sure to have. i also live in arkansas down n malvern . thanks jt
