Hey guys,

Just picked up an '03 ECSB 4x4 with a 6.0/4.10.

The truck has 265/75/16 on it now. I will be pulling a 30'-32' fifth-wheel, ( 3 or 4 times a year) for work purposes. The rest of the time it will be a daily driver getting me back and forth from the job.

Do you think the 265's will be ok or should I drop back to the stock 245's?

thanks!

I'd stick with the 265's. I always upsize from the stock 245's to 265's on all my trucks - really just for the looks of it as I feel that the 245's just look too small. I just put 265's on my LMM last week - took it out to check the speedometer accuracy today. Running at a steady 60 on the speedo compared to about 60.5 to 61 on the GPS so at most, the speedo is off by 1.5%. there is also no problems with rubbing with the 265's and no need to make any suspension adjustments.

I agree with him stick with the 265s.

i would stay w/ the 265's
