space saver for trike everyday?
Its quite difficult to get sticky skinny square treaded tyres for trikes and other light vehicles so why not use a space saver tyre?
They are governed for by the same set of regulations that apply to everyday tyres so as long as the load rating and the speed ratings are suitable
they are OK.
I checked on the Camskill site for specifications and the highest speed rated "skinny" I could find was a Pirelli who do a 135/80/14 tyre
that has a load rating of 80 i.e. 450kg so thats OK but the speed rating is P i.e. 94mph. I guess that is OK for most trikes or light vehicles but
some may have ambitions to go faster.
Anyone know of a higher speed rated skinny tyre?
Space savers have a disadvantage in that they only come with 3mm tread new so the life is short but they are made with a soft sticky compound to give
similar roadholding to their larger bretheren so the traction should be a lot better.
Cheers!

Interesting line of thought!
How do they stack up on price?
What tyres does the Morgan 3 wheeler use - they must be pretty well rated given the vehicle's capability?
Might be some useful info here -

Thanks for the suggestions but I'm really looking for tyres with modern construction and rubber - hence the spacesavers!
I'm wondering how the speed rating is calculated - if the loading is say 20% of the rated loading would the safe speed rating be increaced or is
it a cetrifugal force thing?
Cheers!

^^ Not sure but as they specify a load and speed rating for tires I doubt you can de-rate one for the other...

Space savers are limited to 50mph
Maximum speed of a tyre can be limited by quite a few factors not just load/pressure/heat, one of the factors is centrifugal force. Going back
yonks I once saw a film of a big name tyre on a test rig shedding tread blocks purely due to centrifugal load and it was only equivalent to about
135 mph.

I don't think it works like that at all tbh, I also think the 50mph limit on space savers is more to do with driving around with two different
tyre sizes. Maybe the rating on the tyre is higher?
