Tire pressure advice

[tanman_2006]

My kids sidewalk Chalk or paint stick has worked best for me. I have 1/4 mile of straight pavement in front of my house but I normally notice the chalk coming off by ~100ft. Problem is most tires after 20K of over inflation wont show a big difference but if you keep checking every 5-10K it will level out.

Well I tried the spray paint again and it didn´t work worth a damn. I went 2 tenths of a mile and all the paint was gone on all 4 corners. Our asphalt highways are pretty rough. There is a cemented road with a bunch of speed bumps. Would that work? Its a half mile long but I would not get to more than 25 mph. Is chaulk better than paint? 100 ft better than 2 tenths a mile? This tire stuff is making me thirsty:thumbsup:. um beeerrrr:thumbsup:

Thanks g

Yes chalk is better than paint. I used kilz with a 4" roller, never tried spray paint. Sorry I should have been more descriptive. Also with paint about 200 ft. Bumps will mess it up due to the side wall flex.
My old 99 3500 single wheel had about 10 lbs difference front to rear. The Hummer was only 2 psi different till I added the top, and extra gear, now it's even.

Yeah bumps kill the lines. I usually run 5-10mph to get less bounce.

UPDATE.............. I finally found some chaulk that worked. It seems these tires like 53 up front and 48 in the back. This is with a cheapo 60 lb guage from the AZ/china.

My other observatiion is these AT tires definatly wander around more on the highway than the m+s michelins I had before. Offroad these tires are 1000% better.

I guess its all a trade off?

I just had new General Grabber 265/75/16 AT2 e (load range) tires put on my 95 sub. The drive home was alot different than the drive there with my old Michelins. I checked the tire pressure and they were at 40 lbs all 4. Way too low for an 80 lb max tire I would think?

This is what most tire shops do now no matter what the sidewall says. Thanks to Firestone and the Ford Explorers.

I wish PYO wheels were 1.5 to 2 inches wider.. Sure would make the 285/75s fit better...

Well they aren't wider but with the right inflation and 15k rotations I consistently get 80k out of the BFG KOs on my PYOs.
