It depends
I like AKA premounts, but sometimes the pro-line tires just work the best. I run the calibers sometimes and the revolver too. It depends on the track and conditions. Other times I like I Beams all day long....Or later on in the day...
On tires that wear out faster, like revolvers, who cares if the foam degrades faster...
I had the same thing happen in J Concepts tires. I'm sure it happens sometimes, but yes pro line could use some help in the foam dept.....
