Towing with BFG 315's ??

[buttugly]

Has anyone had power issues when towing with 315's with a 3:73 gear?

None hear. I had a 2000 lb slide-in and about 6K in tow this summer towing from AZ to CO,WY, SD and Utah. It was fine.

Although it appears Fred didn't seem to have any problems, I can tell you that going from stock tires to the 315s will "definitely" give you a feeling of "lost" power ... simple math! I went from stock to 285s and noticed a 4 - 6 mph drop hauling my camper up the same grades I could usually hold at 70 mph in 6th gear. I'll add however that would actually be 2 - 4 since my speedo is off by 2 mph now.



BFG has a link on their website that you can enter the tire sizes on (after providing a little other info) that will tell you "effectively" what the "new" ratio is with the larger tires. Just for an example, I too have 3:73 gears and with the 285s I'm effectively at 3:61 - 3:63 as I recall! :--)

Tow my 10k trailer alot, no worries. It did slow me on the steep hills though However my new Juice/Attitude should fix that. 1600 rpms at 60mph holds it steady with no problem.

Absolutly no problems towing with my 315's. My speedo is off by about 9. 1% so when I'm going 70 I'm really going 76+/-.

Take it the dealer and have them reflash the right RevPerMile for that tire. Seem to recall it being 601 or something like that. Speedo was dead-on after that. Need to go back for the 37's now.

I tow occasionally with my truck and its usually heavy when I do. I have 315's with 3. 55 gears and a 5spd and it handled great. However with one gooseneck trailer I use I have to watch my clearance between my bed rails and the neck because my truck is so tall.

I'll echo what clayton said. Towing is a walk in the park.
