Standard Wheel Width

[PZG302]

Whoops my mistake, I put in 1.5 not 1.3, busy day at work looking at spreadsheets and plenty of data, got my numbers mixed up.

 

Would still allow for an 8" to be used.

Anyway, you need one of the "historians" here, Al Thomas, Gav Doolan, Carl Beck, to give you some sort of "vehicle spec sheet" that shows that these 7" rims, were fitted and supplied, on brand new, ready for road registration 240 & 260 Z's

 

Does it matter than Nissan released the vehicle that way or that the car was fitted (from dealer) with wider wheels? Plenty of US 240z's had the wider peanut style alloy wheels fitted by dealers but were not "Nissan" parts per se..or part of the original spec.

 

Would a Sports Option Catalog help?

Problem is cars like the Z432-R (PS30-SB) or even Fairlady 240zg (HS30-H) vehicles is that they often had Topy steel wheels fitted as standard spec, since the expectation was that the race team would fit their own wheel of choice. Alan could speak to this more than I, as his knowledge on such things far exceeds my own.

The rules now state that you comply with these guidlines.

Rolling Diameter :  + 15mm -  -26mm

"TYRE"Width < no more than 1.3 Wider than orignal.

 

No mention here of actual RIM size at all. What this equates to I have no  Idea.

This is straight off the QLD Transport website. Check it out. I renewed my licence on here so it must be OK.

So that would mean with a period correct 175 wide tyre, or equivalent,  as would most likely have been fitted on the steel rims standard, you can run up to a 260 wide tyre, which means that depending on the tyre and allowable rims easily an 8 inch rim and up to a 10" rim.

 

But, again check with your engineer rather than dodgy interwebs advice.

Not from dodgy site but from QLD Transport offical site. Would copy and paste but got NFI how to do that. There is PDF on minor mods allowed and a section on wheels and tyres.  All up to date as well 2016.

I meant not to rely on dodgy advice from car forums about about what tyres are fitted to what rims from interwebs forums not the source of the info being from the TMR website.

Thats OK mate. I know you were not having a go at me. Just want to steer the guys to the offical gov site.
