Which tire do I buy?

Hi, I'd like to buy new tires with more weight carrying capacity for my truck to pull an 11,000lb 5th wheel. The ones that came with the 2018 Ram 2500 are size : LT275/70r18 125/122s. I'm not sure if that means they are E rated or D. The brand I'm looking to buy are from Westlake. the ones I have are Transforce and well worn. Thanks for your help.

Your tires have a 3640 lb load rating and are a LT E. Plenty of tire for a 11k lb 5th wheel trailer.
I've never used the Firestone Transforce on a truck but have used a couple of sets of LT235/85-16 E on my service trailers. They run around 40k-45k miles till the wear bars get close.

Westlake LT and ST tires don't have a good rep on many different rv and non rv trailering websites. There are better LT E tires out here for your truck. Don't cheap out when tire replacement time comes.

Driving style and city vs rural has a lot to do with how many miles of service a tire will last. I'm rural and can get 75k+ miles out of LT E on my trucks. I also air up (65 psi-70 psi rears) for when needed and air down when empty (65 psi frt-45 psi rears).
My bil has used the same tire brand/type on his 2500/3500 trucks....lives in a big city....squares his corners....aggressive driving and never checks his tire pressures and is lucky to get 25k-28k miles before the tires shoulders are gone.

I stick with major LT or P brands for my trucks. I don't have a favorite brand but lean towards a nice quiet all terrain on my 2wd/4wd trucks.
