hi guys,
why do all the tires i have seen have deep lugs when brand new but say 500 hours in the middle of the tire goes flat w/ still a good 2" or so lug at the edges of the tire? why don't they make the lugs 2 or 3" deep throughout the width of the tires?

AND... can i grind out the center portion of my "mclaren" type tires to put deep grooves back into the center of my tires to maximize the use of them before i recap them? if i can what would i use to grind out the rubber fast?
thanks,
steve

The center wears out early if the tire is overinflated relatively. Don't know about grinding them but it seems like a bad idea to me.

what type of machine SS or tractor?

i have found a fix for both but which one are you haveing probs with?

it's a new (to me) 763 w/ the mcclaren type nu-aire tires. they are actually the ones bobcat sells though w/ the holes around the tire near the bead. i can't flaten the tires because they are solid rubber but can't find a good way to grind back the center tread until i recap them. for anyone wondering...these tires can range up to 800.00 each so it's frustrating to wear down the centers so fast and lose traction when the outside lugs are still at least 2" deep

check with who-ever you bought the machine from because more than likely they were included with a set of tracks:

mclaren will give you a FREE set of tires (i think nu-air) with a set of tracks because when you put tracks on it will set the machine another ~2" off the ground and the bucket attack angle will not be correct and it will "gouge" instead of grade and the nu-air's are shorter to help with this problem

you can grind the tires all you want it will not hurt them and you can do it with the regular tool or you can use a chainsaw looking wheel for your 4.5" angle grinder (but be carefull and make sure all protective guards are in place) and you will not hurt the tire and i would not think you can actually "retread" the air-less tires I'donno

fwiw...i went by BIGFOOT's shop today, they are about 20 minutes from my house..here's the tire groover they use to cut down the monster tires, it's pretty impressive how fast they cut rubber http://www.myerstiresupply.com/pls/myers/display_coupon?pass_cou_id=207&cart_id=fsrb7118

that's pretty reasonably priced too

yeah...kinda pricey...there are some cheaper hot knives out there but i'm not sure i want to spend a week cutting down my tires, i guess i need to buck up if i want it to be easy
