Yeah, especially on-road. We have parking lot races at the shop I work at, and a guy had a set of 40 series beadlocks w/ 40 series road rage tires mounted on them, and after a few runs on the track, they cut through the sidewall. And, this guy has a revo 3.3, but he's soooo gentle on it, and a lot of times, we're wondering if it's even working right, lol. He kinda seems afraid to get it into seccond gear on the back-straight, lol. Now, off-road may be fine, but I'd say no way for racing anyway.
He gave the tires back to us since they were bought through our shop, and we contacted proline, and they sent a new set of wheels and tires, 40 series road rage, but the guy who had the tires didn't want to chance them happening again so he requested proline send him some 40 series wabash wheels...which they did send us.
Good customer service though, at least they stand behind their products. It may have been an isolated incident, I'll find out all the specifics for you while I'm at work tommorrow, and find out what proline's response was and such since I was not the one who contacted proline, but I was at the track when it happened. Cut 3 of the 4 tires...pretty much ruined his day of racing...
But yeah, I'll find out if it was an isolated incident for ya tommorrow woodie.
