The manuals specify tyre pressures for radial and for bias ply tyres, but does anyone have wisdom regards the optimum pressures for the wider rims and tyres that are commonly used today?
As a bit of an extreme example: we have a Meyers Manx clone dune buggy (take a 1962 VW chassis (in our case) and shorten it and then put the fibreglas buggy body on; drop about a thousand pounds and slap 15x7 or 8 rims and associated tyres on it) and I've been playing around trying to figure out what would be optimum pressures for that beastie, which lead me to thinking about our BJ7 with it's 72 spoke (vs stock 48) wider rims etc.
On the dune buggy, I've tried going down the highway and taking temperature readings across the tread width at 2 psi increments (nothing consistent enough to be useful), plus most recently painted white stripes across the tyres plus a band of duct tape and masking tape and electrical tape, trying to look at wear patterns. Again, nothing to really hang my hat on - and it's about six months now until I get to try again.
Any suggestions for figuring out what pressures should be using today's rims and tyres on the 3000? any suggestions for trying to figure this all out?
I'd hoped to find some sort of Internet programme where you could enter weight and tyre size etc. etc., but no luck thus far.
Wisdom? Thanks, Doug
