Tire decision question :

[VX KAT]

Hey Kat!
Been almost a week with the LTZs ... (but not many miles)

They are GREAT i the rain and big puddles! I was lucky enough to have a good storm roll through on Saturday

Anyway, what pressure are you running? My mechanic pumped them up to 45 and I am wondering if thats a bit much.

Kool!!!!! Only a fellow VXer could appreciate the visual of seeing a VX go rammin' through puddles and probably turning and braking! It's just what we do!
I still haven't had any rain since I last posted...so good to know they're good in the rain on pavement!
I've got mine at 40 psi...much higher was too punishing on my dirt/rocky road.

PICTURES! PICTURES!

Tom, yea it seems they can take the higher pressurest ... and to answer your q: yes, stock 18x7 rims ...
I find irony there, being that you lower pressure when going off road, etc.

Kat, Agreed, expected a somewhat harder ride but WOW! the end of my 'street' is gravel and has some deep potholes ... you can really feel it there!

Pics will be posted when I take a few more (and then remember how to add them on here - been a while)

Ironic, yes.

If you're running your tires at or near the max pressure & you hit a nice sized pothole, the tire tries to flex which will increase the air pressure in the tire & you could break a bead (tire pops off the rim ... well ... half way).

You air down off road for increased surface area & to allow the tire to flex more & 'mold' itself over obstacles. The trouble is that a lot of people air down too far & the tire flexes too much which can also break a bead.

In my limited experience, the only off road conditions you really need to air down for is rock crawling. All other conditions, the tread design has more to do with performance.

I am guestimating somewhere between 35 and 40 is probably much better than the 45 I have in there now.

Tom, you should always air down to around 15 PSI for soft sand.
Gives the tyre a wider contact area so you don't bog down so easy.

Spike runs your tires at 36psi is where you live has a moon like terrain.

Mines had the same max psi but never went over the 36 plus that allows me to use valve caps with air monitoring pressure gauges

PK,

I knew I was gonna get some flak on that statement. I won't jack this thread anymore than it already is tho.

You're right. Airing down for soft sand does make a big difference

IF

you have the right tread to start with. I stay away from really soft sand with mine since I have MTs. That tread pattern just digs big holes in sand & doesn't do much for getting you from point A to point B.
