275/70R16 or 265/75R16?

I'm about to buy 16" alloy rims with BFG KO2 tires but am not sure which of those two sizes to go with. I have a stock 06 TRD offroad.

• I'm modifying my truck for overland use so it must be good on and off the road.
  
• Are there any substantial ups or downs to either tire size?
  
• Will these both work with the stock truck without scraping?
• If I need a lift, what is the minimum lift I can get away with with room to spare?

In the very near future I'll be purchasing the OME BP51's so scraping in the mean time isn't the end of the world but I'd still like to know if it will scrape stock. I've read it shouldn't though.

 

Bigger sidewall is better for offroad.

 

The 275 is a wider and just a hair taller than stock 265/70/16. The 265/75 is taller but same width. Both will fit with no lift but a small lift up front like .85" from 5100's would help. There are not very many places or brands that make the 275. BFG being one of the few.

 

The 265/75 is the same width as stock tires?
So 265/75 is well used, liked, and common. Where as the 275/70 is an uncommon size for people wanting to try something different?
Thanks for the tip on lift size.

 

Still running stock but actively looking at replacements myself- so just an observation the 275 is a "D" load tire and is 3 lbs lighter per tire then 265/75/16 which only come is in "E" load tire -

 

Ah so the 265/75s have a tougher side wall with E. That's definitely a plus.

 

I'd go with the 265/75. Very similar to stock but as others mentioned, slightly taller sidewalls.

The 275/70 is an oddity, in my opinion...

 

265/75 is normally very inexpensive as well even compared to to stock 265/70. My last set of Hankook Dyna pros were like $600 otd.

 

Keep this in mind, not only inexpensive, relatively, but easier to replace if you mess up one tire. Never know exactly when or where something will happen and trying to replace an odd sized tire then can become a PITA.

 

275/70-16 is still a 31" tire. For off road you want a larger dia., so 265/75-16 is better.

Neither tire should rub if you use stock wheels. If you get aftermarket wheels with less offset, 265/75-16 will rub mudflaps and maybe the fender flare bottom lip at full suspension tuck.

 

The new wheels will be TRD ones with a 15mm offset. Will that be an issue? What are the stock wheel's offset?

 

^Stock TRD Off Road wheels are 32 mm offset. I have 0 mm Konig Countersteers and they rubbed on the flap. 15 mm should be OK. If you get rubbing, you can always get Huskyliner flaps which have more clearance.

 

I've come to the conclusion to buy 265/75R16s. The larger diameter, tougher side walls, greater availability, and lower price are very convincing. Thank you all for your opinions and feedback. I saw angles I never though of before.

 

I see you just bought your lift! It looks so good. You didn't ask for this, but I would go with 285s and cut what you need to. I went from 265 to 285 and am much happier now. You could also look at skinny 33-inch options - 255/85/16 I believe is one. I don't know if they offer KO2s in that size, but they do offer KM2's

 

Thanks man! I'll keep this all in mind. Maybe when my tires go bald I'll try out some 33s.
