i got my son a year ago a chinese quad.

the brand is a eagle. they called it a 110 but it is realy a 90

it looks just like what they sell now as a mini hummer except ours has smaller 6" rims.

i have been looking for some good tires for it but all i could find was crappy ones .knoby cheng chang one and a kenda that was no better than what it came with.

then i stared looking for AG tires and found a set of snow blower tires made by Carlisle there called Xtrac

the size is 15x5-6 and they fit perfect. dont wory that there not 145x70-6
they are awsome and fit like a glove no problem.

i am running them in the rear only .
i will proably get a Kenda for the front when he needs them. he wont need these diggers in the front.

here is what the little buggers look like

the tread is a inch deep!

you will not be dissapointed . the fit is spot on.

 

That's a hella good price on them too!
