thanks for all feedback
i am thinking to go to bf goodrich at, because the cooper don't have snowflake symbol, and for insurance company if i have an accident this could be a problem.
in this moment i have fitted in my car 255/65r16 and if i go to bf goodrich online they give me 2 sizes 255/65r16 or 265/65r16, but i want a 235/70r16 why they don't show this tires 235, 245...i can fit, right?
Note only some sizes of the BFG AT have the snowflake symbol. you should check out the Goodyear Duratrac. Wrangler DuraTrac Tires | Goodyear Tires Canada Greta all around tire and it has the snowflake symbol. Quite a bit better in the winter than the BFG.
245/75/16 is a better offroad tyre than 255/70/16 especially on sand. Get it in an LT carcass. Cheers
I have duratrac in 215/85r16 for my go play in the snow tyres. Very good but lots more drag on road than Bfg at.Quote:

Drag as in slows you down pretty quick if you put it in neutral.Quote:

They should not. They are just a normal tire. Rolling resistance should be not detectable. If you are slowing down detectably in neutral, there is something else wrong. These tires are no difference than any other road tire.
I'm wondering if you've ever ridden a bike. Say a mountainbike with a variety of different tyres?Quote:

Tyre tread pattern and pressure makes massive differences to rolling resistance. This is why people get terrible fuel economy with mud tyres and better economy with bald tyres than new tyres.
The Duratracs are significantly chunkier and have noticably more drag than the BFG A/T's. They are not far off in drag to the SAT radial retreads I used to run.
They are not a road tyre, while not as chunky as most MT's, they are closer to a MT than any AT tyre and have a softer and more pliable rubber compound than most AT's.

I have four sets of RRC wheels and tyres. In order of rolling resistance.
1. Hankook RA07 (HT type road tyres) Lowest drag.
2. Toyo tranpath ice/snow tyres.
3. BFG A/T and Michelin XPC.
Then a huge gap.
4. Wrangler Duratrac.
Yes. I have been mountain biking for 30 years. There is a difference but not measurable on our application. Maybe in a Prius you would measure a one percent hit in mileage but not in a a Rover.
It's not 1%. It's at least 10%.Quote:

On a bike the difference between almost slicks at 40psi and 2.5" tyres at 20psi is about 10km/h in cruising speed.
