I know these are hard to find but I just got 5 of them, chassis's and bodies.

 

Starting to build the first one and have an issue. I have no idea what rear tires to run on these.

 

With the rear bushings in place and on the jig my largest jig wheels (.812) aren't even close.

 

I did some measuring and from the top of the rear axle to the jig is .480, 3/32 axle is .09375.

I divided that in half and get .046875.

 

So by my math (which could be all wrong...) it's ‭0.433125‬ from the track to the axle center line, which means a tire dia of ‭0.86625‬ would give zero clearance.

 

Again if my math isn't fubar,  to get .062 clearance I need a tire dia of ‭0.98625‬

 

So a .990 rear tire?  Anyone make a decent tire this size? The .062 clearance isn't set in stone as there is no class for these at the local track. I'm building them for me. my nephew and brother in-law to race (plus a couple more for other friends or family members who want to play...) but I figured I'd try to stick to 0.62

 

I see Pro Track has a 1.00 tire but have no idea how good their tires are.

 

Any opinion / help would be appreciated,

 

Thanks.

I use a protrack Daytona stocker, I can't recall if it is .950 or 1" diameter, but it's really narrow. Will measure and photo for you. And my Raceway has them, so we can confirm part and size tomorrow.

3 of us have supertrucks and last Sunday we were having our own little truck rodeo on the tracks! Fun stuff!

The goal is a 5/8" rim with enough rubber (FISH) to be a minimum of .900"+, so Pro track "N" series or B&E hardbody tires (also has a harder tire), or many of the wider drag tires will fit the bill.  Cutting a center tire groove to look like 'dually' wheels is optional.

So that's just about 1" diameter' .600" width on the rubber. Motor is an old super wasp.

Rim's are orange because a friend has a truck company and all his truck wheels are orange.

Thank you to everyone.

 

My only worry with the tires that JK made is how old are they, (JK doesn't list them anymore) and what is the shelf life of natural rubber tires? I have a 1/32 scale JK car I pulled out recently and those tires are dried out and unusable.

 

So it looks like Pro Track tires are decent then?

 

Again thanks for any input.

You have to be aware that Pro-track sells BOTH black foam and FISH- ("N" code).  Treated and wonder are not their option, but B&E Slotsports does have a firmer tire that works well on some tracks and cars.  Hardbody cars usually run over 140+grams.

Thanks for that, these are 0.15 lexan btw If I try Pro Track I'll use the N code tires
