need new rear tires

[OzFab]

I think the 410x350-6 would work just fine

IMHO, that seems a bit pointless & counter productive; if you go to the trouble of replacing the rims, why use the same spec tyres, why not go for something a little more garish?

I'm all for going with something more meaty than the ones already there. I'm just having trouble finding something that isn't a turf saver, although the more I think about it the more I believe a turf saver would be fine. Its not like this thing is going to be a mud kart or something, and its super light it it does get stuck in a little bit of mud.

I really like this combo. What do yall think?

Nice but, a bit extreme don't you think? I mean, going from 11" x3" tyres on 5" rims to 16x7.5" tyres on 8" rims, your clutch will hate you

I would consider something more like this

Thats not a bad choice. I'd say its just about perfect. I just gotta get it w/o those rims. I need a bolt on rim.

I just found recstuff.com
They have a lot of cool stuff, including tires.

Changing to a #35 setup won't help because the tooth couth will be higher meaning the sprocket will end up the same diameter...

I have to disagree with you on this one Fabroman.
Sprocket diameters for #35 chain are 60t= 7-1/4", 66t= 8" and 72t= 8-3/4" while for #40/41 48t= 7-7/8" , 54t= 8-7/8" 60t= 9-3/4"
A 54 tooth for 41 (the smallest ratio one would normally run on a kart) is actually slightly larger in diameter than a 72 tooth for #35 (too high for most karts) The 60/12 or 5:1 is a nice setup for a kart and would have less chance of hitting the ground than any of the #41 sprockets.

A 60/12 setup on 35 chain would give you 13/16" more ground clearance than you currently have, it would raise your top speed and slightly lower the acceleration. It would also slightly reduce the wheelspin potential.

Also, the kenda turf tires wear slower than the carlisles. From personal experience. And resist the urge with everything you have to buy any cheap harbor freight or northern low speed split rim/hub/tube/tire combo. They are extremely cheap, the tires wear really fast, they come with awful bearings and the hubs will fall apart under load if you don't weld them.

Fair point, thanks for doing the research/math.

However, if the tyre diameter increases, so must the sprocket size so, we're back to 72t which, as you so kindly pointed out, is still smaller than the current 54t #41 sprocket.

I actually don't mind being proven wrong, it shows someones paying attention & knows what they're talking about; nice work
