Smile Tire Size Question

This relates to a more recent vehicle...so here goes.
My (DD) truck is an '05 Silverado 2500HD/Diesel and it currently specs out to use/have the tire size LT 245 /75/ 16", (load class E)

However, I've seen a lot of guys running LT265/75/16" tires....
What is the impact of this size change up from 245 to the 265?....just preference? any impact on the speedometer reading or?

Many Thanks!
Coley

Re: Tire Size Question

Colin the 265's are 20mm wider than the 245's so a slightly larger footprint. The 245's are 30.46 inches tall and the 265's 31.64 inches tall. Because of the 1.18 inch height difference there would be a small ( in my opinion ) 3/4 MPH difference in speedo reading.

Re: Tire Size Question

Ive got 285's on my 04 silverado. I will never go back to a skinny tire. Rides down the road SOOOOO much nicer. Plus looks better in my opinion.

Re: Tire Size Question

A large majority of the vehicles I service that came with 245's are now running 265's ( my rigs included) as Already Gone stated, 265's are wider & taller, IMO fill out the fender well a little more & are sometimes cheaper too! Not enough difference on the speedo to cause computer issues.
