So can you fit tubeless tyres on early cars? Are the wheels the same? Do I understand correctly that crossplys can be tubeless?

Yes, but as Geoff says, you need the larger tubeless valve.

You also need to ensure the rims where the tyre butts up to are smooth.

I must admit. I've always used tubed tyres on both my Conquests.

According to the factory Service Parts Catalogue, all road wheels are the same across the range, including whether or not tubed or tubeless tyres are fitted. The singular part number given is 134601.

Assuming you are going for crossplys, I'd recommend the tubeless tyre, as apart from the saving on inner tube cost, the ride will be margially better due to the more compliant sidewall, and less hasstle if you get a puncture (see poem below).

However, as advised earlier - do check the inner face of the wheel rims where the tyre makes contact too ensure an air-tight seal.

I once had a puncture whilst driving down south,
Not in a tyre - but a puncher the mouth.

Conquests are heavy. Why 6 ply tires should be avoided ?

................ But no has heavy as you think, notwithstanding the weight is "accommodated" by the tyre size.

Six ply tyres have much less flexibility in their sidewalls with heavier tread pattern etc. - so the ride would be much harsher. I tried three different makes/ply ratings on my Century and the driving and ride were distinctly different before I chose a set of Avon ply crossply ( four ply).

However, that was some while ago and Avon Tyres are now a brand name only, so I cannot vouch for their product now.

Just a tip on tubes. I found recently that my local tyre dealer that I have used for many years no longer carried patches to repair tubes. I was somewhat shocked at this event! So I have now bought and carry on board a tube repair kit that I bought from Vintage Tyre sales.

Right you are Stan Thomas. I tried my Conquest on the road recently. I think I try look for four plies and keep my six plies on for the time being. Thanks a lot for your advice

It's been a while since I've seen this thread active, but a couple of further comments seem appropriate.

Not all Conquest/Century wheels are the same; those from the standard Conquest with narrow brake drums will not fit the Century with wider drums, although Century wheels probably fit Conquest wheels.

Also, a simple tale about 4 and 6 ply cross ply tyres.
Back in the 1970s we had a Conquest to which I fitted 4 ply cross ply tyres, only to find that the car became exceptionally sensitive to variations in the road surface, for example the double depressed surface imprinted on some motorway lanes by commercial vehicles. On these the car would wander constantly from one side to the other which made journeys on such roads extremely tedious to say the least. At that time the car was an everyday machine, we lived in Europe and found some busy Dutch autowegs a special difficulty for that reason. But the UK was no exception.

"Aha, you will say, "there was a problem with your suspension or steering geometry!" Certainly not, I checked for that, and when at last those tyres were sufficiently worn and were replaced with 6 ply car (not van!) cross plies once again the problem completely disappeared to my relief and delight, and driving the car became a pleasure once again.

Today 6 ply cross plies of the necessary quality are probably very expensive, but this is really no great problem, just forget cross plies and fit radial tyres instead; those intended for SUVs are probably best and 195/80R15 tubeless are the most suitable replacement size for those old 5.70 x 15s. Radials give a very pleasant ride and are not dangerous when the car is driven sensibly.

Cheers

Geoff

Here is another aspect to consider. Tyres all seem to be described as "summer" or "winter". I would assume that a summer tyre is just what we used to call a tyre and that a winter tyre is a specialist product which is of interest only to those of us living in Alpine regions? Is that broadly right?
