Hi all

I went to look at some tyres today for the Dodge.

Originally it was fitted with 9.00x20 crossplies, split rim wheels, but 8.25s were also listed as an option.

question is, the tyres I looked at today are Michelin 8.25x20 but radials, not crossplies, still with tubes. Will they still fit I wonder????

I've asked someone I know who has a little Dodge truck, just wondered if anyone here has any thoughts on it?

Rick

Rick, I checked with a couple guys here that work with truck tires and putting radials on your Dodge wheels is a BIG NO NO!!!

For reasons of safety, please find a set of ply tires!

Radial tyres are used all the time on commercial vehicles. Provided these tyres you have seen are the correct load rating and are new(ish) then there will be no safety issues.

But the main safety issue is the age of the tyre, not how much tread there is on it. If you check the sidewall symbols and discover the tyres are more than (say) six or seven years old, then leave well alone.

Has to do with the age and design of your wheels. Older style wheels weren't designed for radial tire beading and side loads. According to them, older type bead locks, rings, etc, can fail when radials are used.

ok, I just checked with another guy who has 40+ years in the truck tire business.
He said it would depend on the wheel type but suggested using newer wheels for the radials if the truck is to be driven a lot.
For mostly static display, it wouldn't really matter.
He also said to carefully check the hub area and the wheels beads for cracking before installing either tire.
