Hi,
I am in the middle of designing an off road trailer with a hinged lid (we use 2 rv5 oztents) and was wanting to know how much clearence to have betwen the tyre and guard. I will be using either 5 or 7 leaf rebound springs (most likley the latter) rated at around 1300 to 1550 kg and was wondering how much they will sag at their max. loading.
Also what size tyres are you using, I could use 31x10.5 15 but that will make the trailer sit a lot higher and could cause problems with putting a tent on it in the future or I could use 30 x 9.5 15 but then it wont match the tug but will keep the center of gravity a bit lower.
Any thoughts would be appreciated befour I launch into it with the grinder and welder
Thanks

Hi Trev6,
I would go for around 130mm to 150mm clearance with no load at the wheels on the shed floor, you've got to allow for the bumps.
Check with your spring supplier. I've seen many new camper trailers at shows without being loaded with 60mm to 100mm clearance. I don't know how they get away with it.
You mention tyre size affecting trailer height, slinging the axle above the spring will lower trailer height.
Happy grinding and welding.

Lots of variables in your question Trev as the wheel travel will depend on spring length, rate & load. Not only will you have to allow for the max load but also the up travel when hitting a pot-hole etc. Measuring my box trailer it has 130 clearance but for offroad 150 would be closer to the mark. My coil sprung offroad gear trailer has 170mm space to the guard but that was worked out using full compression of the spring & shock resting on the bumpstop.
The tyre size ideally would be the same as your tow vehicle but if looking for something standard then a Hilux 205/16 would be tough enough, give reasonable clearance, easily found outback & not too tall for unpacking the trailer.

Thanks for all the replies so far I thought when i put the question to you all that it wouldn't be easy to answer but I thought it would be worth a try.....and it was.
What I am thinking of using is a spring and axle setup sold online by "Huntsman" trailer parts, there off road backing plates are the ALKO brand I think the rest is from somewhere overseas. My tyre delema is I already own 4 six stud rodeo rims with 2 tyres that would be good enough for a while all I need to do is get another second hand one for the spare, the prospect of not having to
fork out extra $$$ for another set is quite an atractive one, but it wont fit the cruiser hence the question on what others do with their wheels and tyres.
