considering the performance of sweep tires, its price and the high wear effect in JV, the sweep tires are ok. No wonder Sorex is the best. btw, I found the pre-amounted sweep inserts are a little bit soft. So, I want to buy tires only and put into harder insert.
I satisfy with the performance of traction.
For my case, I consumed a new set of sweep tires 32R within 20 runs in JV (1 Set $120)
Around $6 / 10min (Not durable, not that cheap at all)
