no, radial tires don't have the cords work against each other like bias
ply do.

if you're driving a honda and using the recommended oil, you're wasting
your money.

See, if it were me, I'd have the oil changed instead of getting
iridium plugs, and a tuneup instead of aftermarket struts. I'd also
replace an oil seal before the whole car. Clearly we have different
priorities.

I guess the 2-3 mpg improvement I get from inflating them to 39 psi
is from positive thinking! You folks can't have it both ways: if high
inflation ruins the handling, it must also be affecting the rolling
resistance. ;-)

Depending on the type of oil, I change it between 3500 and 5000 miles.

Hmmm,
He saves little on gas at the cost of uneven tire wear and waste it on
oil change, LOL!

I have literally never worn out a set of tires. I retired a 9 year
old set of Bridgestones with 90k on them for sheer age, and will be
doing the same with a set of tires on another cars. You trolls should
read up on tire maintainance.

 

Here's the thing about tire pressure, try it, inflate your tires to within 4
or 5 lbs of cold sidewall pressure when they are cold, burn a couple of
tanks of gas, how is your mileage? how is the handling? don't like it, let
the air back out you may be out what a dollar for the air?

Try it instead of accepting what other say, I have low rolling resistance
tires @ 40psi (44 sidewall rating) and see a 5 mpg (12%) increase in mileage
in MY car. There is no change in the ride (except it does not feel like the
car is dragging) handling feel is fine, braking is great, and yes I do drive
on dirt & gravel roads to no detriment....in fact, I even drive in the snow
with these same "overinflated" all season tires with no problems. Oh, by
the way, I change oil when the car tells me to, no sooner, no later.

I don't claim to know everything, it would be far too big a burden.....I
know what works for me, that is what I am relaying.

The type of oil? What about the type of driving?

My type of driving doesn't vary much. So I go by whether I'm using
non-synthetic, or synthetic/synthetic blend. I've gone as much as 7500
miles on full synthetic in the past, but nowadays that would be a full
year's worth of driving.
