Kingpin Crossply Tyres

[Spacemud]

Noticed today that the spare on my series IIa is a Kingpin crossply. All the rest on the vehicle are Olympic Pathfinder Radials. Question is, should I go back to Crossplys or stick with radials?

Comparison of Radial vs. Cross-ply performance

This little table gives you some idea of the advantages and disadvantages of the two types of tyre construction. You can see the primary reasons why radial tyres are almost used on almost all the world's passenger vehicles now, including their resistance to tearing and cutting in the tread, as well as the better overall performance and fuel economy.

   Cross-ply   Radial
Vehicle Steadiness   tick   cross
Cut Resistance - Tread   cross   tick
Cut Resistance - Sidewall   tick   cross
Repairability   tick   cross
Self Cleaning   tick   cross
Traction   cross   tick
Heat Resistance   cross   tick
Wear Resistance   cross   tick
Flotation   cross   tick
Fuel Economy   cross   tick

Sorry about the mess above, I tried to do a table in HTML, though despite HTML code being on, it didn't come out.

Have a look at the table in this link:

How many miles do you do yearly / weekly / monthly?

Looks like I'll stick with the radials then!

Vehicle is used daily, to and from work, this is about 5 miles away. Any further and I think I would be bankrupt due to fuel costs!!

As soon as I can afford it I will be fitting an LPG system!

I had kingpins on my truck when I bought it - the previous owner had fitted them to a) keep the truck original and b) to lighten the steering.

However, I found then very hard - and on the road they tended to slide and follow every rut (Quite scary at times  :? )

I changed to BFG ATs - quieter, more sure footed (no tram lining) and as said - better MPG.

I do think the Kingpins would have lasted forever as they were solid but overall - I would suggest radials!  :P

Err, crossply's if you do a lot of laning, events etc, radials if you like the road, or motorway and just occasional lanes

Decided on a Olympic Pathfinder MT in the end to match the rest but couldn't find any. Eventually went for a Colway MT and can you believe it - the tyre tread pattern is EXACTLY the same. Reckon it's the same tyre bar the name!
