Hi I just got an Amp MT and was looking to get tires with Foam inserts I was wondering if anyone had any knowledge or a good brand I could search for

Proline make great tires. The trenchers are good all around tire, the badlands are good off road tire. Duratrax makes good tires too, like the lockup, or sixpack. You might want to get new rims too, a 2.8 is more common and has more tire selection. You need a 1/2" offset, like the rear of a traxxas stampede or rustler. The 2.8s will be a little taller, so if you go that route you will need to drop a tooth or 2 in your pinion to keep a similar top speed.

Sorry for being ignorant, but what do you mean by drop a tooth in the pinion? That means to use a different pinion, right?

Correct. "drop a tooth/add a tooth" means to either use a smaller (fewer teeth) or a larger (more teeth) pinion. (AKA "gear down/gear up")

The diameter of the tires affects the gearing of the car. So when you install tires that are taller (larger diameter) than the stock tires you will likely need to gear down to compensate.

okat thanks for clarifying 🤜. Would you happen to know if 2.8 wheels fit on the amp? Cause someone said the body had to be trimmed first.. i Want to get some big, 2.8 preglued wheels for my brushless amp so it can look cooler, and run better. (very sorry for taking over this thread a bit, but this thread is about wheels so it’s kinda in the same topic)

Sorry for the delayed response. Larger diameter tires and wheels will fit-- and as you mentioned you may need to trim the body to provide clearance. The only other thing is the hub offset-- the interior of the wheel might rub on steering links or other hardware while turning so watch of this.

Okay, thanks for the response, all good. I’ve never worked with custom bodies and trimming, so would I have to purchase a hobby knife, Leona scissors, or any of that stuff? Or could I just use regular scissors?

To trim a polycarbonate body (a typical RC car body) you'll want to use curved polycarbonate "body" scissors. They have short cutting blades to make is easy to cut tough polycarbonate and to cut out tight curves. Impossible to do with regular scissors.

You can find the scissors at just about any hobby shop and they're relatively inexpensive-- about US$5.00-7.00
