I am looking into what the narrowest tire that will fit on a daily driver '03 Taco DC 4WD, v6, auto. We are looking to gain some MPG by cutting down on friction loss on the highway, also the stock size has let us down in hard pack snow. Want to see what size tires on stock suspension and wheels will dig down throgh the snow to get us great winter traction.

 

i had 245/75/16 cooper st/c's on my 03, i liked them pretty good and got up 22mpg towing a trailer

 

Is 245 stock size for your truck? We can get a fair amount of hard pack here in Northern New England. The Taco does not cut down to the ground hard enough with teh wide stock meats.

 

If your stock tires are 265/70/16, (Roughly 31 x 10.5 x 16) switch to 245/75/16 (which is 31 x 9.5 x 16). 1/2" on 4 tires will help and the 245's are cheaper to buy too.

 

235/85-16 would be great too (9.25" x 31.7"). Check it out on tire rack. You can get BFG's, Dunlop's, and several others.

 

265/70/16 is stock and if you want real narrow go with the 235/85/16 like hodge said
