Running 275/70/17

Thoughts on 275/70/17 tires

Looking to get new wheels and tires for my 23’ DCSB OR. I currently have Bilstein 5100’s all around and the front set at 1.1” lift which leveled it out with the back. I’m currently on stock tires and wheels and have 1.25” spydertrax spacers which I’m not opposed to changing or getting rid to help with offset and clearance if needed.

Ive seen a lot of controversy about 275/70 tires and only being available with a heavy load rating and how that impacts the ride, MPG, loss of power, potential rubbing etc….

I’m thinking of setting my Bilsteins up front to the top notch giving me a 2” lift and then a 1.5” AAL in the rear to still keep it leveled pretty much. I also have the OTT tune set at mild/medium.

My thinking is with the lift and the OTT tune that should take care of some of the rubbing issues and the loss of power, MPG issues. Not entirely of course but should help out right?

What are your guys thoughts?

 

I personally like the size but you're right, they are 90% BFG tires for a reason. It's just not a common size.

It's why so many go 265-70R17 It's headache free and literally every tire comes in that size.

 

Read up on the cause of the rubbing. Lift does not fix it. Tunes also won't help with mpg loss to a bigger tires

 

That’s why I was thinking going 265/75/16 but i really like the bigger tire size 275/70/17.

 

Lift doesn’t clear tires and tune really doesn’t help with tires much. Tune just helps the throttle feel less laggy which in turn makes the truck feel lighter to your foot psychologically, but the tires are still making the same power robbing effect regardless. Of course, it is slight, but still.

Personally, I don’t see a good reason for 275/70R17. It offers very little additional benefit over 265/70R17 or 265/75R16 and includes some cons like the limited load ranges and tire options. It very often rubs the control arm on stock wheels, and if you get aftermarket wheels then usually the rubbing is moved to fenders.

 

Can always do 255/80/17 (33"x10")

 

I’ve thought of that but can’t get past the skinny tire look. I’m picky I know lol

 

There is something to be said about universality, especially when out of town.

 

I’ve been running 275/70/17 for three years (?) and love them. Perfect size for these trucks. The E-load BFG’s are bulletproof so you do not have to worry about flats in the bush. Also good highway manners, and you can put a cheap 255/75/17 (exact same diameter / stock Jeep tires) on a steel rim as a spare and gain some ground clearance in the back with the thinner spare. Can keep your mudflaps as well.

I get a tonne of compliments on my truck for “looking right” with this tire size. For sure not as bro as a 285/70/17, but also no rubbing (on a 7” wide wheel with no spacers) and the spare fits with no hammering or exhaust chop, and the mpg hit is not crazy, and your steering box is slightly less burdened than with a bigger tire.

I did the Whipsaw Trail in BC on these tires. Not bad for an IFS Tacoma with 1.5” of lift and 32’s.

Ultimately, there are as many answers as there are questions when it comes to tires, but 275’s are perfect for my uses.

 

The 275/70/17 look great and what I plan on going to once my tires wear out

 

275/70/17, factory lift , trd rims, General ATX tires.

 

I have that same setup and wheels. Currently running 265/70/17. Any rubbing at all? How far off is the speedo?

 

Absolutely no rubbing. I haven't had a way to check speedo. Doesn't ride or as quiet as my Murano but neither is my Vette. It's not noticeably noisy and rides like a lifted medium size pickup.

 

I have a 23 TRD sport with 275/70R17’s on 17x7 SEMA wheels with a bilstein 5100’s on the top notch (supposedly 2”) and 1” in the back. Rides great with the new wildpeak at4’s. I see I have a 16” spare, what’s the closest common tire size to put on there just in case I need to use the spare, since I’ve still got the stock spare for 265/65r17’s. What’s the best tire size to put on the stock spare?

 

There isn't anything that close in 16in as 275/75/16 doesn't really exist. I picked up a Rough Country steel wheel that was 17in and threw on a 275/70/17 underneath. As someone stated up in the thread you could also look for a 255/75/17. But your options are severely limited if you're sticking with the factory 16in wheel.

 

As long as it was close I’d be happy. I’d rather not buy a wheel, but if I could find something cheap and used that was close to the side I’d do it. That way I could get the tire fixed by discount or put my old tires on if they need a few days to get another tire.

 

You don’t need a spare tire of the same size. Your differential will get along just fine for the short duration use of a lessor or larger size tire until you get the bad tire repaired. You’re most likely seen those very small spare tires on sub compact cars that say don’t drive over 55MPH. If you look carefully you will also see the same warning on our Steel rim spare tire. What to look out for is if you increase the size of the brakes and a 16” rim will no longer fit. Some larger calipers require a rim larger than 16”.

 

I did a lot of research and didn't find much in the 16in wheel size, so feel free to do your own, I just wanted an identical tire. If you're fine with being 2% off then just get a 265/75/16. Trust me these are not common sizes for a 16in, 225/90/16 is a trailer tire for example:

 

Yeah 2% to me makes no difference in the 5-20 miles I’d be driving to get it fixed. I’m going to look for a used 265/75, which should be pretty easy to find.
Thanks for the help!

 

*-Wildpeaks are available in C and E rated in 275/70/17. I have the E load with Fox 2.0's and the Sema wheels. I only have rub while at full lock if the suspension is cycled
