Matching tyres/rims for trailer and tow vehicle

Basically common sense I guess, It's nice to have the option available to mix and match your tyres. I had the occasion to help out a mate who had a Disco, my Camper had Disco Tyres, I loaned him my spare from the camper after he ran out on the Oodnadatta Track.

Personally, I would fit both Hilux and camper with 16 x 8 rims and the 265/75R16 tyres of your choice.
You will never wear out the tyres on the camper unless you put them on the Hilux too.

If you want compatibility then begin to consider the OD of the tyres too.
Some vehicles don't like uneven sizes. Diff internals don't, if run fast and for a long time with different dia. Also upsets TC, ABS and ESC if they are required before returning to normal.

The camper rim offset is also a major factor as the Hilux is + offset and the Camper is,?????????? Even if the tyre sizes (and stud pattern) are same same dia, having spare wheels doesn't mean they will be interchangeable. ie, camper wheel may not fit or will foul when placed on a steering axle.
The centre of some rims have a different curvature as they meet the rim and it also can foul on brake calipers and brake drums in some cases.

The wheel nut taper also has to be checked,ie, angle and depth and face contact position.

If same rim dia is used then perhaps only carrying the spares as tyres (no rim) is an option but changing skills and tyre tools are then required. You have them anyway.
You can fit stuff inside the cases to assist storage too, therefore a weight saving of no rims.

The added advantage of having identical rims and tyres is that usually you wear out the tyres on the car long before the camper/trailer. You can include them in the rotation to share the wear so to speak.

I would specify to the CT manufacturer that you want the axle/hubs made to take your 17 inch Hilux wheels and tyres, with the Hilux offset. That should address the caveats that Ross M mentioned.

I bought a second hand camper whose wheels do not match my tug. It has not been a disaster yet, but I always have to carry extra carcases, etc when it could be so much simpler.

Did that with our caravan's wheels - exactly the same as the tug - because the tug could carry two spares when I bought it, I ordered the van with one spare - 3 to share on the rig. And of course, Murphy has seen to it that we've not had a flat in 5 years with this rig :-)

I just finished today converting my camper trailer from 16" RRC/D1 alloys to D2 alloys.

Not an easy job with ALKO 10 inch electrics with Parallel bearings.

I have never used the trailer spare in many thousands of Ks but it is insurance.

IMHO if the trailer spare is a little out in diameter it is not a deal breaker as remember it is a remote area emergency use option after 2 tyres have been damaged beyond repair with string . Better a tyre say 5% different than a rim. I have 255 70 x16 on the car and 205x16 on the trailer, 8 inch rims on the car and 7s on the trailer but the bolt pattern, offset and hub centre size is the same.

I had 10 punctures on my Cape York trip. Lots of speculation as to why but I just think Murphy had hitched a ride.

Anyway I was glad the camper and the car had matching wheels.

JOS, Did you say stock standard rims on a Hilux with 17"? Which Hilux has 17" rims..?

Great idea matching tyres and rims. Back in 1989 a mate had a trailer with the same size wheels as his cruiser but the only down fall was it had ford car wheel bearings which stuffed up on a Cape York trip. The guy that fixed it told him to get the same bearings as his Toyota when he gets back to Cairns.
