    Default 245/70/16 vs 265/70/16 tires

    I have 245's now and am looking for the first factory tire replacement of the Duelers. As far as price, both sizes are about the same. The 265's will give me about another inch of lift since the diamater is 1" higher.

    Will I experience a drop in gas mileage and will it look better, or should I stick with the 245's?

    yeah you'll probably experience a little drop in fuel mileage but I doubt it will be anything major. Will be a little different look being a little taller and a little wider tire.

    265/70 is really a good size tire for these trucks, mine came that way stock. I dropped a bit of mileage when I went to 285, so I imagine you will drop a bit too going from 245 to 265. If it concerns you a lot then stick to the size you have, but I'd rather have 265. I think its well proportioned for the truck.

    thanks for the input. my intuition is telling me go for the 265 tires. btw Erki, your truck looks good with the 3" lift

    My 05 V6 Tundra came with 265/70/16. On the interstate, I would average 21-22 mpg going 75-80. If you are planning on leveling the front end, the 265's will look good. Take a look in my gallery. My front end was raised/leveled 2 inches with 265's. Good luck!!

    1" of diameter = 1/2" of lift

    should also look into 265 75 16. Ive been running that with my front 3" lift and looks good. As well I believe it fits in with the stock height so if you decided to level out the front it would still look great.

    Man, your truck looked so different back then, cool to see what it looked like before and after you went off with the mods. Hmmm, great idea for a new thread!
    Here is a pic of mine before M.A.D.ness kicked in full blast. 265/75 16 and yes, 265/75 will fit on stock and looks even better.

    I have a question that might help the OP and others that are interested in the 265s. The 265/70/R16 is an optional upgrade over the 245/70R16 for some 1rst gen tundras and many of the benefits have been stated. If the OP upgrades to 265 what steps are involved to ensure speedometer accuracy? The Toyota service manager that I use did not have an answer or solution when upgrading to the factory optional 265s.

    Good link. I was also wondering about the speedometer adjustment. From what it looks like, it should only be a 1-3 mph difference from actual speed (varies by speed and wear of tires though?)...

    I've never bothered to worry about it since its is only a few mph different. I would more wonder if going from like a 30" tire to a 35"
