I am getting towards the end of a 2 year renovation of a 1973 Saab 94 V4.
I have had the standard wheels shot blasted and powder coated silver.
I am thinking of fitting 165 80 R15 Continental CT22 tyres.
Are these tyres ok and do I need to fit inner tubes??
Any up advice will be much appreciated.

If your car has its original wheels they accept tubeless tyres. I have no experience with the Continentals you mention.

Hi Ian.
I have those tires on soccerballs and they seem to be OK with no rubbing. Soccerballs are 4,5" so if you are fitting them on 4" rims they might not clear the inner fender/wing at full lock. I think 4,5" steel rims came around '76, but I'm not sure if the offset is the same as the soccerballs.
Regards, Mads

What's your experience? Nothing wrong with inner tubes in the correct tyres in my opinion. Some say it's best to avoid inner tubes in tubeless tyres, which makes sense as they're not designed for them in the first place. If you need them with tubeless wheels with tubeless tyres there's an issue that needs fixing anyway...

I'm running Yokohama Blue-Earth 175/65/15 on soccerballs, no rubbing (and wear is pretty good now I've got the tracking sorted)

When thee tyres (usually tubeless) have ribs inside them and you use tubes the ribs chafe on the tube, and that creates issues. Tube type tyres are (as far as I know) always smooth inside.

I think that you'd be hard pressed to find new tyres that are specifically made to be suitable for tubes. Rims for tubes, always I think, have a bigger hole for the valve. There are bigger valves for these tubed rims but most tyre places won't have these if you are going tubeless. Don't find out after they have taken the tyres off like I did. I wasn't aware that I had tubes on my Amazon. Luckily the 2 replacement rims I was having fitted had the larger holes so the tubes could go back on again. They are still there but one tends to lose air due to being a bit porous. It's not punctured. Also have a set of the large valves for when a new set of tyres comes along.

Only two stroke and early V4 wheels (up to MY67?) need tubes; you can't fit tubeless tyres on these as they don't have a groove for the bead. I think I've scrapped all tube-wheels I had, in my opinion it doesn't make sense to use tyres with tubes any more (although my tyre guy assured me he can still get radial tyres for tubes, forgot what make, and I have a stack of cross ply tyres that need tubes).

When I first bought Betsy, she had tubes fitted. I just presumed that it’s how it was, so after deflated experience I opted for tubes again - without success.
I think tubes had been used because it’s an oversized valve hole. Never changed the tyres and they are tubeless and all has been good since.
