......tires....

I am a new member but have been lurking for about 6 months so.....at the risk of being kicked out, I have a tire question.

I purchased a new to me 2009 31 foot Keystone Hornet TT in September 2013 and have spent the past months dialing everything in and getting it ready for travel. I was planning on replacing the tires since I don't know their history but today I finally found the date code which is March 2011. There is no evidence of cracking or damage and good tread. I've had no tire problems in the 3000 miles or so that I've towed it so far. The tires are Carlisle DuraTrail 225/75/15.s Load D rated at 2540 lbs. the camper is about 8500 dry and almost nothing loaded (actual weight at scale the day I bought it). I have 2 trips planned in 2014, one of about 2100 miles round trip and one of about 5000 miles round trip and likely smaller more local trips as well.

I have two questions. 1) Is it worth it to replace the tires despite only 2 years and appear in good shape? And 2) should I worry about increasing the load capacity since I'm likely to be near 10000 lbs once loaded. (I will be getting it weighed again before taking off) Carlisle has the same size tire but w 10 ply E rating with 2830 lbs capacity.
  • Aside from the obvious issue of costs$$$, I would explore 16" rims and "E" rated tires. In addition I would look into the Good Sam Emergency Road side policy, if you don't already have it. The best $120 per year investiment in your future peace of mind as you RV:)
  • More tire is always better but you'll find that the combined ratings of the tires is usually lower than the gross weight of the tt. Not all the weight is carried by the tt tires, a percentage is carried by the tongue and tow vehicle. The manufacturers account for that to put lower rated tires on their units.
