I'm guessing the answer is no but is it legal and most of all safe to fit scooter tyres on car wheels?
Dimension wise they safely fit 125/70/10 on a 10" x 5" wheel and just about my only option if I want a slightly lower profile than just about the only narrow car tyres available for 10" wheels.

No matter whether it's legal or not I can't see scooter tyres being capable of withstanding the loading you'd place on them if used on a car. It's like when people stick car tyres on caravans and then wonder why they fail.

Good point i forgot about the load rating aspect.

Even if they were safe, most bike tyres are very soft and will do a couple of thousand miles.
I imagine that figure would plummet being used on a car (or tiny pickup).

scaryoldcortina (where is he now?!) fitted a pair of motorbike tyres to the front wheels of his 'Mayday' Austin special he built. I can't remember any more detail than that though

Bike tyres will not have the load rating and possibly speed rating necessary.
Apart from anything else the profile would be completely wrong. Vintage bikes used squarer profiles but not available in modern small sizes.
Bad idea all round.

ooh nice suggestion and thought that would sort me out but getting a similar problem to car tyres - they're aimed more at wider wheels. I think I'm happy with how it looks / will look on the 145s now any way.  |

Best option for narrow tyres are vintage ones or space savers, but both are unlikely in 10".
As with the bike tyres, speed ratings and load ratings are very important.
Can I ask the reason for wanting so narrow?

Can I ask the reason for wanting so narrow? The wheels are 5" wide so I want to tuck nicely with it lowered, I'm happy with the width really but just trying to get lower profile for more lows but you can't get 145 in less than 80 ratio so i was investigating 135/80 or 135/75 etc to try and drop my overall tyre diameter from 19". |

Have you looked at high speed trailer tyres? Again you'd need to check load ratings.
Can you get any other rims to fit? I.e. 8" tall ones?

Some older cars, 1920/30's did use bike tyres but then the cars weighed very little and top speed was 40 and that was only down a very steep hill I wouldn't use bike tyres on a modern car.

When I was looking for tyres for one of my trailers, I found the tyre size was a common tyre for ride on lawn mowers, which aren't suitable for road use. After much searching I found the ones I needed, listed specifically as 'high speed trailer tyres', not because they go quicker than the average trailer, but to differentiate between them and the mower / garden trailer tyres of the same size.
But, I have a feeling that you only find this problem when you get down to 8" tall rims.
My trailer tyres in question are 16.5 x 6.5 - 8 (yes, that is all imperial). I can't be bothered to do the maths, but they are less than 80 profile...
