Replacement Tires on XG32 Question

[CTRvs666]

Has anyone ever replaced the tires for a higher load rating? I now have 23K miles on my XG32 and 3 of the tires are spiking (dealer term for the middle tread wearing out first) but there is a lot of tread life on them. The tire pressure is good and has been maintained.

The dealer felt that the coach is too heavy for the existing G rated tire. He suggested that I go up one or two load ratings and replace the tires.

Has anyone had the same issue? We live in the hot desert and you can't have any tire issues when its 110 and the asphalt is probably 175.

Look up the cause of how your tires are wearing then decide if your tire guy is right.
I'm not sure he his.
I know very well of the same issue but it wasn't related to weight.

If you trust him, he will suggest the best trailer tires he can warrant.

The dealer is an aligment center that only does medium duty, big rigs, busses and motorhomes. and above. He doesn't sell tires. One of the smartest guys on alignment, load, suspension, and such I've ever met. Crazy busy and booked out about a month. When I had my rig in there he was aligning 4x6 BLM Wild Fire Trucks.

He thought I could drive these tires safely for another year possibly more. I am going to drive these for at least another year.

Your tires are 19.5", correct?

What psig are you maintaining? Steer and drive?

Which was the 3rd tire with center wear?

In the past i ran many vehicles with 19.5's and never wore a tire center

Most were at 115 psig

A far too narrow rim can cause this but 19.5 is pretty well standardized so I doubt a 31x10.5 on a 4inch rim relates.

You can’t just use the pressue on the door sticker.

You need to weigh your coach and use the Continental document that specifies the tire pressue based on front and rear weight.

I have an SV34 with the same tires and is heavier than your XG32. Using Continental’s recommended pressure for my front and rear weight, I’m running 85 - 90 for the front and 95 - 100 for the rears.

I have no wear issues at 20,000 miles.
