Why do you think you need bigger brakes than a trophy truck? Sure, your truck weighs more than a trophy truck, but unless you sink MAJOR bucks into it, you won't be going nearly as fast. I'd be much more concerned with spindles and hubs than brakes. If you haven't priced those out, brakes are the least of your concerns.
More braking capability is always a good thing. I know I will come up far short of a TT in suspension capability, but I'd like to improve whatever areas I can... Improving the brakes is an area that is likely within my means. So I am looking for input on the other areas that will be impacted by the move to the larger brake combo, namely the wheels and tires. Honestly, I was hoping that the spindles and factory 3/4-ton hubs will be strong enough...
You will have a very small side wall with a 37/20, heavy vehicle= pinch flats.
Everybody would love to run a bigger brake package, but you sacrifice that with a bigger wheel and more likely pinch flats.
That was one of my major concerns with the 37/20... and that is why I was looking for input from anyone who has run that size combo on something other than a mall crawler... At the shows and events I regularly cove guys are running 22s with 35s and I hate the low profile MT tire look and know that would be pushing it way too far.
Looking at the basic math a 35/17 combo has about 9-inches of sidewall while a 37/17 combo has about 10-inches of sidewall and a 37/20 combo would yield about 8.5-inches of sidewall. It would sacrifice about 1.5-inches of sidewall from my current 37/17 combo, but would only be 0.5 inches worse than a 35/17 combo which a lot of people run so would it really be that bad???
I obviously don't have the money to throw away to experiment so I was hoping someone else already has...
Thanks again for the continued comments, everything will help me come to a conclusion...
