tire size

[laxncampers]

we bought a used 2008 rockwood ultra lite TT. blew out 3 tires in 2 trips. mechanic said the class c tires were too small, and whoever did the inspection should have picked up on that. has any 1 else had similar problems?

Load it up and go to the scales for some accurate weights. I suspect the tires you have on it are Chinese made something or others. Get them off and buy Maxxis and go camping. There are hundreds of pages concerning the cheap Chinese made tires that are placed under towables and the many many issue with them.

We have a 2007 Rockwood Ultralite. This summer we had 2 blowouts on the same trip home. The remaining 2 tires didn't look so good either. Long story short, ended up with 4 new tires (a Goodyear, and 2 model years of another brand that I can't recall now) thanks to the tire replacement service guy who opened up his shop late on a Sunday afternoon just for us. The mix of tires was because that was all he had in stock for our wheel size. I blame the problem on cheap OEM tires that barely meet the GVW of the camper. By the way, our camper was not over loaded when we had the 2 blowouts.

I will ride on my mixed variety of tires for a year or two, and then invest in higher range Maxxis or Goodyear tires.

We replaced our 215 C's with 225 D's this year and much improved the ride and smoother tow. The D's are rated at 2500 lbs. at 65 psi. although I run 58 psi in the 4 tires and the GVW on our TT is near 4500 lbs. I too would stay away from Chinese tires.

kevinC,
This is what I am hoping to do also, but I'm unsure of the increase in tire size (215 to 225). Did you have any problems with the larger tire fitting? Were you able to keep the same wheels or did you have to upgrade those too?

I put Freestar 225/75 15's "D" and as I mentioned they are rated at 2500 Lbs. at 65 psi. Freestars are made in California by Tireco Inc. I had Carlisle 215's but they were "C" rated and I was concerned with tire performance, plus, the trailer was not stable under windy conditions and my tire guy said to expect better handling with 225's. I believe the 225's were like an inch taller, so that was only a half inch under the wheel well and not an issue with clearance. So far am very happy with the performance of the tires. We just came back from 2200 miles in 2 1/2 weeks and the trailer pulled like a dream. The tires are still new with maybe a total of 3500 miles. I mostly drive 55-60 mph at trailer GVW around 4500 Lbs. and am still playing with tire pressure, but this last trip I went from 55 psi to 58 psi and the pull felt better. hope this helps you.
