They certainly wear, but from what I've seen the grip is worth it.

And you really can't beat the price. Even if we have to replace them six times they'll be cheaper than our wheels last year.

Re: pic: Wheel progression

I'll get a picture of our drivetrain wheels, but we are seeing similar wear on the tire version of the diamond tread on both our practice and competition bot. The grip these suckers had when they weren't worn (and they still have decent grip) was great, but we're going to drive the practice bot a little bit more aggressively than before to see if the wear on the wheel is affecting its performance. It'll be a pain to switch the treads on the wheels, but if we find we're getting significantly better performance using the blue nitrile or SBR tread we used last year, we're ready to do that switch.

Re: pic: Wheel progression

With this kind o fwear happening quickly on the diamond tread pattern, why not switch to the W-tread? It' has a higher CoF and is ever so slightly cheaper. The advantage of the VersaWheelDT was supposed to be their resistance to tread wear, but if that's not actually the case, I don't see why you'd use them* over the regular VersaWheels.


*If you're using the 3.25" variant, obviously, it's your only choice.

Re: pic: Wheel progression

We saw similar wear on our wheels... we have a 6WD wide bot (not sure if our center is dropped, I don't believe so).
The center wheels look pretty good, but the outer wheels were about as worn as the 2nd wheel from the left. This was after 4 or 5 hours driving in our shop and ~10 matches at our district event.

Our driver was having a lot issues pushing around the point they started to look like that. I see your point so I'm not entirely sure why they were slipping so much more.

Aren, is there any reason that a team couldn't treat a 'worn' Versa Wheel DT as being similar to a Colson and cut their own tread pattern into it?...

Teams may try whatever they like, as long as they send me pictures
I can't see any reason you couldn't do this.

Re: pic: Wheel progression

Would the wear nullify the whole premise of the drop center regardless of wheel material?
