Thread: 130 tray height to avoid wheel rubbing

Could you measure the distance between the axle housing and bump-stop, add a little more for when articulated as the outside of the tyre will end up slightly higher.

Than add say another 50mm.

This wouldn’t be the minimum height you need between the top of the tyre and underneath of the tray.

Another consideration is what size tyre you are wanting to run long term, if your planning a taller tyre than you will need to add this in.

Some trays are mounted in-necessarily too high

Mine is a 110 but I suppose some dimensions would be the same.

I have standard 235/85/16 tyres and initially had a problem with rubbing in cross axle situations. They didn't rub if the axle was level, only when one rear wheel was up and the other was down.

My alloy tray has 40mm deep stiffening ribs underneath. Those ribs are 180mm above the top of the spring tower. I used an angle grinder to remove a small path of the ribs where the tyre rubbed.

So that patch gives me 220mm above the tower and the problem hasn't returned. The top of the tyre is about 40mm above the top of the tower.

Hi,
D130 cab chassis sometimes carry a camper.
My rear tyres used to touch a 45mm deep wooden support for the tray planks. After cutting that out I have 200mm clearance unladen and haven't touched since.
Cheers

The box on my 130 is built the same as a generic aluminium tray, it has 100mm longitudinal members sitting on the chassis with lateral members approx 40mm deep sitting on that. The standard tyres that were on it (sorry can't recall the size, think they may have been 7.50/16) used to rub heavily. I added a second 100mm channel section under the existing, to improve both the tyre clearance and the departure angle. Now with 255/85 tyres it has plenty of clearance.

I went out and measured my tray tonight, I have never had the tyre scrape the tray and I've had it on full articulation plenty of times. Suspension is standard Puma.

Tyres are 265/75-16 pretty much the same diameter as stock

My old 130 ‘95 vintage rubbed so I screwed a sheet of reinforced rubber to the alloy ribs above the tyres - stopped the horrible noise and the amount of tub time is small so it never wore out

Current 130 ‘09 vintage I rebuilt the tray so it could have diesel/ water/ spare and a parts drawer underneath... I made it as low as possible with twin 75L tanks and the spare but it still has plenty of clearance - no rubbing

not quite mounted at the bare min for clearance. I can fit 2 x 35" tyres under the deck, leaving the deck free for canopy and storage

Thanks for the replies - they are very helpful! It looks like my tray is at least 50-70mm lower than other similar vehicles and so a minor adjustment like grinding off the strengthening ribs won't make enough of a difference.

I also took the suggestion of measuring from the axle to the bump stops - it is the same as the distance between the wheel and the bottom of the tray, so with a the bump stop squishing a bit and some axle articulation I probably need an extra 50mm+ of height on the tray. I might see if I can jack up the car on the weekend and get a better idea. (Or revisit my Year 8 triangle geometry!)

The up-side of raising the tray is that I will then have room for water/fuel storage and/or a drawer. The down-side is having to do it at all...
