Running a smaller tire is pretty much a personal choice. It will affect ride and make sure you look at the load handling on the tire. I know on mine I was going to go to a smaller tire but when they put them on and lowered the truck down the tires egged at the bottom. The same air pressure as I had in my old tires just a little more narrow of a tire.

Hey thanks for the response, I don't see the lowering problem as on tirerack.com they are the same diameter at 31.6....basicall a little narrower and lighter....again thanks, CSM-H

you aren't going to notice improved gas mileage.... you will probably suffer in the ride department.

Hey thanks for the response.......I am still hoping someone who has actually done this will respond. There is a difference in weight and price.....CSM-H

going to a tire with a shorter height would raise the power band of your vehicle. i.e. rpm's will increase because of the diffrence. likely eating more gas. but, you will probably like the power increase.
if i want to save gas on my vehicle, and not compromise anything else (horsepower, driveability etc) go check out the vehicle spec tag on the drivers side door, and use the tire size it says on it.
spennrocks, thanks for the response...but I am not going to a shorter tire.....narrower, not short, they are both 70 series only the width is different 265 down to 245..... and actually the 265/70/70 (on the truck) is taller than stock which is a 265/65/17 tire......again thanks, CSM-H

I've not done it...and wouldn't as I'm not willing to give up any handling. That's where you'll see the biggest change by losing that width. You'd probably see a similar fuel savings by going back to the shorter OEM size as you'll gain back some gearing. I went with 265/70's when I replaced OEM tires but I think I'm going back to 265/65's this next time. I went to the 70's mainly because was it was $50 cheaper (and they looked a little better) but my mpg dropped by 1....which = $320 in fuel over the 25k miles I've had them.

the width dimension (265/245) does have an effect on sidewall height.
skinny2, thanks for the response....Now your comments do make sense and I will take a look at possibly going back to stock...the 265/70's were on the truck when I bought it and I don't like the ride as it is.....thanks, CSM-H

In most cases I would agree, But as I mentioned before the diameter of the tires is the same as 31.6......so it's a moot point. again thanks for your earlier response, CSM-H

I didn't notice a change in ride going from 65 to 70. Typically you'd expect the ride to improve going to a taller tire, but I think the suspension will effect this more on a truck than anything else. Tundra is tuned very nice in my book...not too mushy or teeth rattling.
skinny2, for the most part I would agree on going taller [with a little width] improving your ride, obviously not too wide.....But you are probably on to something in the going back to 265 and there by not having to go into "it" as deep to get this heavy truck (DC 4wd) going.....
For my part I just think it is tread design of the tires I don't like.......but after 57 cars and trucks in my life (so far) I've got a reasonable handle on it.... ya I know I need a support group for having so many vehicles.....CSM-H

dougg, welcome to the board. Just so you know there are three tires sizes available for the Tundra; 265/70/17 is an optional larger tire, 265/65/17 and beliveve it or not the 245/75/16....So I don't think the size I am looking at would be a problem. CSM-H

Almost time for new tires, different size?
