I just cleaned up the 4 regular wheel rims from my 1966 P5 Coupe (3 litre) in anticipation of buying some 185/80/15 tyres and noticed a difference when I got to the spare wheel rim. The four on the car have the center wheel section welded to the metal rim, but the spare is secured with 3 rivets on each section. I will be buying tubeless radials, but might the rivetted one not leak air? It might have come off a 1964 parts car I got with the coupe. Do I need to look for a welded wheel? Ken

Whether you can fit tubeless tyres or not depends on the rim. My 1957 Austin has rivetted wheels but they are definitely tubeless. I think it likely that it is a tubeless rim despite being rivetted. I can't imagine Rover were still on tubed from 1958 onwards when Austin were already on tubeless tyres. Having said that I tend to fit tubes anyway though these modern ones from the Far East aren't a patch on the old British-made Dunlops - I still have a Dunlop tube from the early 70s and it is so much thicker and heavier. I keep it as a reminder of a past age when British meant quality, nowadays everything seems to come from China and its neighbours.

Rover did cahnge over to tubeless about 1958 on the P4's and rivets were used. The Rostyles made by Rubery Owen were desiged as tubeless - welding is cheaper than rivetting but probably both are equally effective. I have not come across any welded ones though but this process is used, as are bolts, when the wheels are refurbished

Thanks, I'll have a go at tubeless when I get new tyres fitted soon.

I just finished shopping for tyres and bought 5 new Cooper P205-75/R15 as the closest modern equivalent to the F78/15 size tyres that were on the car, and they seem a good fit. I bought whitewalls since the car is such a solid single dark color (Pine Green). The one rim that has a rivetted hub is tubeless as you suggested. No sign of leaks so far! Ken

Hi guys, has anyone had any difficulty with air-sealing issues on the rivetted wheels. I still run tubes on the rostyles fitted to my car but would prefer to run tubeless.

I've never had a problem with air-leakage from rivetted wheels in the past 40 odd years. Proceed with confidence!

I have heard of problems but never experienced them. They were designed to be tubeless as are the tyres so tehy must be used in that way

My rivetted spare wheel and tire are still holding air 9 months later without needing a refill. Ken

Guys - what tyres are we currently fitting to replace 185x15s?

As far as I'm aware we are still using 185/15 radials, and this size is used by the majority of owners. A minority use the nearest equivalent to these and that is 205/70/15.

There are still plenty of suppliers out there of 185/15 at all price ranges and this was the agreed nearest equivalent from the outset. The once more common 205/70 x 15 was only used as they were cheaper and easier to to obtain being fitted to XJ6's etc - they seem rarer than P5's now

I recently went to 205s as these were available at almost half the cost of 185s.
The 205 whitewalls were around £57 each, Vredestein 185s were quoted at £97 each.
