Alloy wheel sizes on a Super Custom

My rx8 alloys aren't selling so I'm tempted to chuck them back on, wind the steering lock stops out and see what it looks like

When you get a chance and the wheels are settled can you measure the ride height of the front for me please?
Wheel centre to wheel arch.

I'll check by eye but as mine is definitely rising now it would be good to know the standard height at the front. Could you measure both sides please? Thanks in advance!

Don't forget to check the wieght rateing as your insurance may not pay out if they do not comply.

I've already wound the front down GPW, turned about 25mm down on the threads

Ah OK Mick I remember now. Not to worry, now I know where the bup stops are (and how close they are) I can make some judgements.

Not sure how I'm going to raise the back until I take out the springs and measure - if I think Rav4 standards will do it I'll probably use those as it may be easier than cutting up rubber spacers to go under the spring assy.

I will measure the level moment later though so I can calculate extra length at string vs extra height at wheel.

The VIA load rating on Japanese wheels should always be on the outside of the wheel somewhere (so a wheel fitter can see it), for instance:



The tyre itself will also have a load rating, note that the max load is AT the max pressure: I..e the tyre in the pic has 750kg only when inflated to 50 psi.



Wheel strength is one thing, fatigue is another and excessively bumpy roads and low profile tyres stress the alloy more and can result in fractures over time - like James's May's Volvo in Top Gear's Africa Special.
This is another reason not to run on the bump stops

The Export certificated weight of my SC was 850kg at the back (425kg per wheel unladen) and 1050kg at the front (525kg per wheel unladen).
With a 80kg driver then the front wheel load is 505kg which on mine gives a margin of 185kg per wheel.

TBH on the Hiace I wouldn't go below 690kg wheel rating - also there seems to be a good selection of wheels with that figure based on a scan of a few forums. On a longer wheelbase or camper you need to weigh your vehicle.

Steel wheels will be safer IMO as they bend rather than crack but are not so available.
