Not that you can't tow with a 37" tire.

I'm sure some people tow heavy with the '40s, just not me.

I switched from my stock to 3.42 gears and put 4.10 gears in.

I like them with the 35" tires; if I had the 3.73's from the factory, I definitely wouldn't have switched, but I didn't like the 3.42, especially with the 35" tires.

I wouldn't suggest deleting your grid heater if you live in a cold climate.

Just grab your heater bolt and wiggle it every oil change, and if you're worried about it, change the bolt out every 50-75k miles.

It's cheap and doesn't take very long.

Just my 2 cents.
Thanks!

I couldn't resist the 37s and ordered some.

35s are probably more logical.

Mostly tow a 5k lbs enclosed motorcycle trailer, so it probably will be ok.

Also, occasionally, I'll like to tow a 16k lbs equipment trailer when my track loader needs serviced.

That's once or twice a year for 60 miles round trip.

Hopefully, it won't be too sketchy on the 37s.

If it is, I'll swap out the stock-size rubber.

I will keep the grid heater.

It gets cold here.

Saw -30 F this winter!
