RPMs per tread type ?

Post by snomon » Sun Jul 01, 2012 10:58 am

I have a slightly odd question , that Im wondering about as it seems Im having a bit of a problem trying to find a balance between offroad tires and regular street.

What Im ideally looking for is tire in either scenario that rolls well ( not necessarily the fastest under speed - because i cant push fast due to my disability ) but something that is going to give me the most rpms off a relatively weak ,or average push.

I dont need this for offroad just now, just street / flat surfaces.

Is there anything that could achieve this using 8" air pressured tire , or would i be better looking at allmost a hard plastic instead ?

You want something with a center bead, when pumped up only the center bead comes in contact with the road, and in lower PSI's the rest of the tread joins the contact patch and gives more grip. You could try -

GI Maks - from what I've heard they have the best of both
Primo strikers - good center bead but not the greatest grip
MBS T1 - a bit of both, not amazing in either cases but are widely available.

I'd recommend once you find desirable tire to clean the bearings and use Bones speed cream. It reduces friction and i believe it would give you the best results for weak to average push.

So let me ask you a hypothetical question.

if grip wasnt concern , and you were riding on the flat ( typical pavement or mall ) with no adverse conditions , just straight and you had achieve a maximum distance under - say 20 pushes ( taking as long as you like ) on tires with no larger a diameter of 9" - what wheel setup ( if you could customise or create any, using any material etc ) would you choose or create ?

Then let me ask you the same question but using one of these instead :)

thanks

Bones is just a lubricant, I clean the dirt and grease out with denatured alcohol, let them dry and coat them with the speed cream. I swear by the stuff. Think it will help you out no matter what tread you decide.

I'd use 8" airliner tires. The center bead thing sounds nice but I don't think it works in practice.

good point with the rodies but i have no experience with them...id go for Strikers. but the bearing comments should not be looked over they make a massive difference.

Thanks for the feedback everyone - pity I dont know any one with some spares to test it .

Is the mbs shop the only place selling them ? ( Im in the uk ) and would these work ok with tri spoke hubs ?

Thanks, I think I'll need all the lube I can get for the task ahead.

Would you recommend putting this stuff on new bearings too? Or is that not necessary?

Thanks!

I've cleaned new bearings and applied it.
I just tested my new trampa bearings with factory grease vs old bearings that the last time I cleaned them was last fall and applied speed cream. The old bearings spun 2x longer, they are due for a cleaning and reapply. They usually spin at least 3x. Time to pull out my pickle jar of denatured alcohol :)

Yeah but new bearings are never going to roll like old bedded in ones

True, but the stuff works great. Just my opinion though. You'd notice the differerance if you used it. Believe me or don't, doesn't matter to me, I'm not a sales rep or anything :rolleyes:

You know ,I just came across these while looking for an adaptable motor i could use with kelly controller.

So it got me wondering if these might be better or worse than my current
own which are 7. 5 " m10s..

From the little I know Im inclined to think the M8s at 8" would give me more bang for my buck as theyd be easier to roll / push off and require less pushing given the 8" increase , or am I off the
mark somewhere ? ( Trying to think of similar heavy loads that require ease of push like wheelbarrows :P )

cheers,

snomon

NB* m8s would be for manual use - not with motor

Also wanted to ask about the Abec rating of the bearings if it would really make much difference to someone going as slow as me - unless I was using a motor and required more rpm?
