265 too 285

[99denali]

Didnt anyone notice a difference in power or gas mileage in going from the stock 265/70/16 to 285/75/16? Just wondering if i need to look out for anything when i buy my new tires, thanks

you should be fine, my winter tires are 265/70/17 and my summer tires are 285/70/17. i don't notice a difference at all, the 285's just way better.

I never noticed until I jumped to a 35

ok thats what i figured but i figured id ask anyways.

im on 295/70R17 n my MPG sucks.... I need to install some 4.10 gears to level out the taller tire. Should improve the MPG and my speedometer reading

 

[bowtiefreak]

it is a fullsize truck, milage sucks period.

I had a stock (with bolt ons) 350 with 3.73 gears 33s......milage was 12.5

have now a 383, 35s 4.56 gears........milage is 12

If I baby the truck the milage may increase by .5 or so

back on subject, you will be fine. Just don't drive like a pissed teenager.

Cars are made for driving like that, not a big denali.

Ive got 31 and went from 425miles a tank on the hwy to 325 now with my 31s im thinking about going back down to 285 with new wheels when i get the money

 

[99denali]

What? 285's are bigger than 31's. you got worse with your 31's?

 

[95slowhoe]

How can a 285 be bigger than a 31, when 285 is how wide a tire is? The first number is width the second number is height and the third number is rim diameter. You would need to know the second number to say it is bigger or smaller than a 31.

well a 285-75-16 is = to a 33-10.50.16 well close to it its a 32.9 i think lol

...hmmm


so then...I went from a 305/40/22....to a 265/65/17

The truck will be quicker..but lose top speed...I wonder if I'll notice better MPGs though?...also, I can turn sharper now..and without rubbing!!!

 

[99denali]

If you read the post you would know that i am getting 285/75/16's and instead of typing that all out i just put 285. 285/75/16>31.

 

[BlizzardX23]

I cant stand small tires...285s are so small..and the 265s that Im running right now are just dumb....I miss my 305s...but Im going for a different look for a little bit

 

[sparkey]

I have a 97 2 door tahoe and when I bought tires for it I was told that because the way the truck sits the 285's will rub in the front but again it's a 2 door

 

[bowtiefreak]

I rub 35's sometimes... it happens. Trim it up and or crank it up a little

I'll let you know how it goes. I've got 265's now, but I'm throwing on 285's and some pretty heavy steel wheels tomorrow. My baseline on a stock '99 4dr 4x4 is about 14.7MPG with mixed use driving. I'm usually toting around an 8 month old, so I have a pretty light foot. How you drive has an awful lot to do with how many MPG's you're getting. I'll post the results as soon as I burn through another tank.

My Tahoe had 265s and I didn't like how small they look in the wheel well. I now have 285s and love them. I didn't notice any difference in mpg at all but they do rub however its not rubbing hard enough to feel while inside the truck and it is not leaving any wear marks on the tire. The taller tire did give me some trouble last year while elk hunting. I hit a hard bump on a 4x4 road and the right front tire went up into the wheel well and bent the inside edge of the fender and chrome molding so I had to straighten it out with a hammer.

 

[h0tr0d]

Did you crank the tbars at all after installation?

 

[Mcoffey24]

I didn't adjust anything. I did have two other people with me and all my gear so I think that's why it hit.
