Does it really matter? He has standard 19.5" MH tires used on hundreds of different model MHs.

So you might have wiggle room, most don't unless they have 16 ply

Stupid idea to regrove a motor home tire, right up there with a recap

Way to much dammage when failures occur

There are exceptions to everything regarding obviously

Again most single axle motor homes don't have a lot of excess capacity on either axle

That is a fact

Retreading is removing the the worn tread from a tire carcass and adding another cap, those caps do fail and are seen lying along the highway.

You are correct in that most of the road gators seen on hot days are caps

New treads come off as well if over heated

Unless you put in some serious miles, your tires will need to be replaced based on age before they lose thread depth. The rubber slowly ages and loses strength. Most sources recommend that you replace RV tires, or semi tractor trailer every 5-6 years regardless of miles. The NHTSA recommends 6 years; my tire guy also recommended 6.

No. Regrooving does not add rubber. It extends the existing grooves into the existing rubber.

About. I had a 68. The problem was in wet snow the front wheel wells would fill with snow so I couldn’t steer. And the stuff turned to ice so was a bugger to remove. Had it in CT. Suspect Maine gets similar wet snow.

Replaced it wit a 70 VW, which was all around awesome and brought my little family to ID, where I dwell today. And only own 4x4s…except RV which is almost as good w dual rears.

I agree that regrooving is not retreading, and is often okay. The tires are built with enough rubber that the grooves can be cut deeper after normal tire wear makes the grooves too shallow. But I don't think the narrow sipes can be effectively recut, and these help with breaking. RVs (mine is a dually with no tag axle) don't have all the extra tires that trucks have, and I'd worry about a reduction of breaking action. So I'd opt for safety and replace the tires, even if the tires were worn down in only a couple years so that rubber deterioration wasn't yet a factor.


You might still be able to sell them as used tires, as most trucks can use them on the trailers after regrooving with no problem.

I've noticed the same problem with my Smart in deep snow: it can't sterr worth a... darn!
But with rear engine/rear wheel drive: it is as good as any VW Beetle was in the snow!

A while back I saw a classic beetle for sale that already was set up for towing. I’d only recently bought my Wrangler though so passed on it. It would be an awesome towed though…

Everyone seems to think "regrooving" is not a good procedure for RVs, and I agree. If you are shopping for new tires I would recommend Walmart.com. As A place to shop. I normally buy mine on line at walmart.com and than have them install them. (You must take the online receipt to them for the lower price mounting and warranty). I like their mounting and balancing policy. And their warranty. I am sur many will laugh but hey I mam cheap and not ashamed of it. It is my money I like to keep as much as I can. Check with your local Walmart if they do RVs.

It was getting hard to buy 13 inch snow tires for the 1967 Fiat 850 Sports Coupe. When I moved south I was able to buy an new set of Pirelli (185R-13), which I had recapped once. I put 143,000 miles on that little car and never had a tire problem.

A car is not an RV. I have run cold processed recap tires on a car. I would not use them in 100* to 105* temps.
