Speaking of tires - interesting article

Doesn't that depend on whether it front or rear wheel drive or AWD?

yep Michelin had a contract since beginning to provide the tires. you know they change them after just one flight. Michelin and labs at nasa got used one to do testing, destroyed

The idea is that with shallower tread and in wet conditions there is an increased possibility of losing traction. If you lose traction in the rear. no matter FWD or RWD or AWD decreased traction in the rear could lead to oversteer and the average driver is more likely to lose control in a skid with the rear of the car swinging out.


All this is theoretical. With only 2,000 miles on one tire I don't think it makes much difference but I said that new tires (more tread) on the rear is general practice.

Personally I like oversteer better. But I have been sliding around in the snow and mud doing motocross, offroad trucks, side by sides my whole life so countersteer is just an automatic muscle function. But the normal uninvolved driver freezes up so understeer is the safer condition.

Yup, That's the concept.


With current car design the results of a frontal impact is much more "survivable" so if you lose control it is "safer" to go off head first than to spin out and hit rear end first. At least that's my understanding of the concept for the average "uninvolved" driver who is distracted by the radio, video screen and phone conversation.

calibration of a tire gauge? hows that possible? maybe on the way over priced units.
as to anti lock brakes. might try learning to drive first. do not want to lock up your brakes? just do not use so much pedal..
worried about a slick road. slow down.

Our plant used to make the Aluminum powder for solid rocket boosters . Later passed on bids we were using totes and drums, other plant was blowing powder into rail cars. More prestige and highest proven aerospace quality than profit. Later had to fast track product for the smaller rockets that separate boost sections and steer them away from the shuttle. Other plant botched the job some how.

When I was a flight deck troubleshooter on the F4-B/N aircraft, the tire inflation pressures were 300# ashore and 500# aboard carriers. The tires were aircraft 22 ply rated Goodyear's.

The inflation rig mentioned was called a "stand-off". Its normal calibration cycle was 30 days.

For decades we have purchased gauges from GH Meiser, the product name being "Accu-gage". There are many configuration options. I can send these back to the company and they will recalibrate them for a small fee. In the past, they have discounted the per-gauge fee if you send several at once. Worth it!!

What about TPMS ?

Tire pressures for daul tires need to be the same

Our over the road trucks basically run fully loaded outbound and empty inbound. Obviously we do not adjust tire pressures.

Thanks World Cat25.
Good article, Calibrating and exact pressure in the Dualies. I didn't think it was that critical. Will be a lot more careful in the future.
All the best,

I recently replaced the tires on my DP at a large truck and fleet tire dealer. When I asked to what psi they would inflate the tires I was told "the max psi." I then requested he print me a copy of the manufacturer's tire pressure tables and showed him the front and dual psi based on weight. When I asked why they would inflate to max he responded "that's what we always do." He told me I was the first motor home customer he met who referred to a chart.

Why did you get that one as opposed to this one?
