Re:New Gen Jimny Tyre size

Lambert wrote: Cars with low profile tyres are different to SUVs with high profile tyres. The standard fit for the gen3 is a 205 on a 5.5j rim. It is possible though difficult to find the recommended rim size for every single size of tyre from every brand as they are legally bound to provide it. As a general rule though the rim should be about 70pc the width of the tyre give or take ish.

So a 215 tyre which has a width of 8.46 x 0.70 (70%) = has a minimum wheel rim width of 6.4”

Just trying to understand this guys. Very ambiguous! Would be helpful if tyre manufactures stated a minimum rim width

Like i said it's only a rough idea. Many people are running 235s on standard 5.5 rims without issues and just as many will have a 7.0 aftermarket rim with the same tyres. I would not be bothered with a 215 on a 5.5 rim. Thing is that off road tyres are designed for narrower wheels to minimize damage to the rim from riding against rocks. What tyres are you looking at?

Thanks lambert, that’s what I had thought. Many people on the forum have fitted larger tyres with no issues. I’m looking at 215/75/15’s which I think virtually all gen.4 owners have fitted with success.

I just wanted confirmation that I wouldn’t be stressing the tyre or at risk of de-beading whilst off-roading

I can highly recommend 215/75/15 - Toyo open country AT PLUS. The PLUS is their latest tyre, designed to be a happy compromise on/off road.
They have great grip off road, good wet cornering abilities, reasonably priced and have an aggressive look to them. They are also amongst the lighter weight AT tyres available.

As we have discussed before, the weight of the tyres plays an important factor in regards to 'blunting of performance' and 'fuel economy'

Ive said it before, but I can highly recommend these tyres, they have been great. Just a suggestion anyways.

Cheers.

I personally wouldn't mount anything wider than 195/80R15, the narrower the better for almost any purpose, probably except the looks. But I understand that to find a M/T for that size is quite difficult. The Toyo Open country A/T 195/80R15 is a very good option.

Speaking just for the gen 4 jimny in this situation, Im struggling to understand how 195's over 215's in all but snowy conditions would be a better choice. Surely more rubber in contact with the earth would be better in an off road enviroment.
