I'm sure it's been asked before but search isn't helping me out this time :doh:

Those Federal M/T's are looking juicy at only 250 a piece right now.

Yes it is possible. Your factory 275/60r20's are 33inches! A 35in tire is only 1 inch taller from either side of the rim. I think 35's are possible factory but may rub in a tight turn when shocks are compressed.

Also, a 275/65r20 are 34.05" tires. And they are alot cheaper! the 35" tires are usually 34.7-34.8" tall and with a heavy lug they wear down to 34"OD pretty quickly. Look into the 34" if you want a tire to last more than 30k miles!

I work for Goodyear so this is more than an educated guess. And BTW, the factory GY tires are made to OE or Ram specs. Not completely GY's fault for a cheap tire!

Also, PLEASE be careful running that Chinese junk. There is a reason for them being $100 per tire cheaper! I could get into rubber compounds and fillers but just trust me! STAY AWAY FROM CHINESE MADE TIRES!!! Your family will be riding on those tires and really $$$ per mile, you will lose more than $100 per tire!

That's interesting, sorry to jump in. I had a 2010 1500 with the 20's and I never knew they were actually 33's. I now have a 2011 2500hd but those are 31's??? If I go to a 35 will they slow me down much? and what are the pro's and con's if any? Thanks.

35s are possible, but 12.5s won't fit without spacers or a wheel with less backspacing than the stockers.

Also, Federal tires have been around forever. I'd have no issue in confidently running them on my truck. A lot of tire prices are that "Goodyear" or "BFGoodrich" on the side, and their advertising, and their sponsorship costs etc. I'd depend more on individuals reviews.
