I don't know what the numbers mean so what's the differance between these two Schwalbe Weathermans...


3.50-10 59p and 100/90-10 61p


......and yes , thank you, I am aware of the problems some of these have had....

[dave411]

Well,one is 59p and the other is 61p,so i would say,2p

Thanks, but I'm none the wiser...

3.50 x 10 is imperial tyre size, 100/90 x 10 is metric width and profile size (100mm wide, 4" give or take and 90% of the width given to the sidewall height) still on a 10" rim. Codes are weight and speed ratings as the graph provided points out.

[Timbo]

Great thanks, understand that now, so the first tyre is half an inch width smaller...and has a lighter maximum load...

watch out with the 100/90, might be wrong, but seem to remember putting one on some wide rims and it rubbed on the casing, due to the width.

100/90 are a better fit on SIP tubless, I've got them on mine and no rubbing issues

Did you have rubbing issues with a 3.50 x 10?

No, but then 3.50 x 10 is a narrower tyre anyway so less likely to rub.

Only time I have experienced rubbing with a 3.50 x 10 tyre was with Schwalbe Racemans that were running at less than 35psi, which is probably why so many people have had issues with Schwalbes and they have since published recommended pressures that are far higher than we have traditionally used
