(NA fourseater that needs tires too)The principal reason to do so is to approximate the tread >pattern that was present in the early '30's....very Luggy, if thats a word. The motorcycle tires I am considering putting on my toy do have a closer to original profile and get more rubber on the road than a current tire. I do know of 2 people who run their pre-war Singer's on Avon sidecar tires and they are very happy with them. I thought about it since I need 6 tires and they are less expensive and had not thought of the safety factor. These tires may leave more rubber contacting the road which theoretically should make them safer but bike tires probably were not designed to handle

the weight and potentially the side loads of a bike tire. Mike (who is glad he didn't order the tires yet) Date: Tue, 24 Feb 1998 Terry, I have bought Avon's for my PA. I called Avon in England to get the right "luggy" look like the factory photos of the 30s. , and they advised that 400 19 were available as a motorcycle tire that was rated higher than the original car tire. Was I given bad advise? They look great, but the car isn't on the road yet. Plenty of VSCC cars here in the UK use Avon motorcycle tyres. They seem to work really well on a light car like an Austin 7 in the 17, 18, and 19in sizes. Sidecar tyres are not sufficiently popular for me to have even seen them. use them to trial, hillclimb, sprint, race and on the road. Date: Wed, 24 Feb 1999 I thought most people using the Avons did use the sidecar tyres. square section tread as opposed to normal motorcycle tyres that have a rounded section to the tread.

The SM's when introduced were considered a reasonable step forward in tyres for bikes as they were reasonably soft sticky rubber - in

As trials tyres they are great, a bit wider than a Dunlop K70 350x19. They were also good on the road when new. after a few trials at 5psi pressure, the side walls are completely knackered and they are now not really safe for fast motoring (over 45 The SM II's are a less knobbly tyre and I use them for sprints and racing. They have a great handling characteristics, loads of grip but at quite

high slip angles, go the car does drift about !!!!!!!!!!!! The Avon sidecar tyre is just that, they are surprisingly narrow. tend to look OK on standard Austin 7 saloons but are not known to be a great tyre, and are perhaps best avoided NOW THE IMPORTANT BIT 1. Don't even think about using modern bike tyres for anything other than trials 2. There is some debate as to the safety of using bike tyres on Austin 7s. It seems that if you spin then the chances are you will invert on the wayFrom a racers point of view I think you must make a judgement Years ago when I bought the Avon SM1 400x19s, they were the same price as Dunlop 400x19 B5 pattern.

We published a photo taken of the car at the point of no return during the Motorkhana [ Driving test ] there is just too much grip on the side walls and not enough slip, consequently this wee beastie rolled. The driver was OK although with a bruised ego, the M type was the worse for wear after rolling. might have the photo in his collection, if he has I'll scan it and frighten you out of the Motor Cycle Tires idea. Wouldn't want to damage the 'N' would Subject Re: Motorcycle tyres > Whats the list wisdom on this....I've heard that cycle tires should > NOT be used on automobiles for safety reasons.....any thoughts? The tread pattern on motorcycle tyres tends not to be flat in cross-section to cater for the bike leaning over on corners; obviously is not so suitable for cars. However, there are hundreds of Austin Sevens running around on sidecar tyres, which do have a flat cross-section as those machines don't lean over.

Just to add my twopennyworth to the debate, I use 3.50/19 Avons on my highly supercharged (15 psig) Ulster and it wanders all over the place, it has a dual-shocker front end and isPutting on small wheels with wide tyres spoils the looks and as I only use it on the road at the moment (shame) I'll stick with them, even if they don't! The Australian "Raid" cars of the 80's, used Dunlop Racing triangulars, with virtually zero contact patch, I think they were ok and they did 100mph.

There has been much made of this accident and that of an Ulster at MalloryBy using these examples, it is claimed that 15 and 16" tyres are the only safe way to go with A7s. It is absolute nonsense. The Mallory accident was a result of inexperience (quoted from the driver). And the Loton Park incident you describe had nothing to do with the tyres (despite the fact they were 20 year oldBy all accounts, had the diver had modern slicks he would still have had an accident as he left the braking far far to late. James Diffy has been going as fast as anyone in an A7 of late in the VSCC,
