Will 17" tires be adequate??

The engine in our '09 F250 (V10) just exploded yesterday while away on a long road trip. By the grace of god, it died about 5 minutes from my BIL's house in Vernon BC after we traveled way up past Jasper to near Edmonton. Could have happened in the middle of nowhere. :E

Through BIL's connections, we've found a very nice '12 GMC 2500 but it has 17" wheels. Our F250 had new-ish 18" Michelins on it but can't swap them over.

Will 17" tires have enough load capacity? Our TT is 7K lbs with a 950 lb TW. The tires on the GMC are off-road looking type and I don't mind replacing them anyway (except for having to spend even more $$). I'd really hate to have to buy new rims too though.

Last two trucks have been Ford and GMC is new to me. The price is waaay to good to pass up and the seller is taking our old F250 off our hands so we don't have to figure out how to dispose of it. The plan is to get the new truck to drive the rest of the way home. Our TT is getting towed home by BIL's friend for cheap.

Gotta get a new truck pdq because we're heading out in a couple of weeks for our annual extended trip and have all the CGs booked in Oregon & Washington.

  • Thanks for the reply. I don't know the load rating on the GMC or our F250 and will have to check tomorrow. The tire load capacity only just occurred to me this evening.
  • What is the 'MAX Load Rating' stamped on sidewall of tires

    I have 17" tires on my 2007 3500 SRW
    3195# max load rating at 80 psi
    5th wheel wet pin weight is 3080#....right at 6200# total weight on rear axle and tires. (14K 5vr)

    Your 7K TT with 950# tongue should NOT be an issue for tires

    Course.you didn't post size/rating of those tires so READ the SIDEWALL Ratings
