Tire question.. .so im running Toyo Open country MT 35x12.50x18's right now and Im looking at running the Toyo open country ATII Extremes, and the two sizes im looking at are as follows.

Tire Size, Weight (lbs.) ,Tread Depth (1/32") ,Inflated Overall ,Diameter (in.), Inflated Overall Width (in.), Max Load Single / Dual (Ibs.), Tread Construction ,Sidewall Construction

LT295/70R18 , 64 , 16.3 , 34.3 , 11.8 , 4080 / ,3750 , 3P+2S+2N , 3P

35X12.50R18LT , 81 , 17.0 , 34.5 , 12.5 , 3415 / - , 3P+2S+2N , 3P


So the major difference is the 35's weight 18lbs more than the 295's but have the exact same construction... i see the 35's have slightly deeper treads by .7 which ends up being like 1/64" more ...and the 295's have higher pressures and load capacity. I also know the 12.50's will be a bit wider like my tires I have now.

Im all for the narrow tire is better, wider isnt always the best school of thought.

They both are the extreme pattern so really im thinking the 295's might be the way to go. What say you smart people. btw I think the 295's are a bit cheaper too by maybe 50$ a tire.

Thanks
Bruce

It looks like the 35s have a lower load rating. I'd be going with that one. I'm assuming the higher load rating on the LT tire will mean stiffer sidewall.
Funny thing is they have the exact same build profile. but im not worrying about ride.. Im lifted 7 inches on Icon Remote Res coilovers.. ride quality can be adjusted..

Sounds like the 295 is better in every aspect based on the stats you posted. Lighter, cheaper, same construction, higher load rating? I like the look of a wider tire, and like the road handling of a wider tire, but 295 is 11.8" wide so it's not narrow by any means. On an 18" rim that shouldn't be an excessively tall, narrow tire so I would imagine it handles just fine on pavement and should give you plenty of sidewall to air down and flex. I would imagine also that 17lbs lighter would make a difference in MPGs.

Its probably because the 35x12.5-18 is not the same size as a 295x70-18.

295x70-18 = 34.2598x11.61 inches

So the same construction may be the case. I suspect a slightly small tire can probably handle loads better in this situation. Larger tires with the same wall will yield higher stresses.

I'd also have to agree with Showstop's speculation on tire sidewall flexibility.
