Puncture susceptibility

45mpg! That is very high. You must drive quite slowly, not knocking you at all, but that is way above average for the vehicle.

Lower pressures and/or different tyres are likely to impact mpg.

What is the exact cause of the punctures? This will tell you a lot about if different tyres would work better or not.

It's an off-road car, but the stock tyres aren't designed for off-road use. As the "highway terrain" name suggests, they're heavily road-biased, with the same kind of build you'd find on a family hatchback.

Even mild A/T tyres are likely to completely eliminate the problem you're having.

Hello all. We got our G4 SZ4 because we live 1.5miles up a forestry road. It's on standard wheels/tyres. No mods except underseal. This is the machine's natural environment but it suffers from a lot of punctures, three in the last week.
I've been driving that track in standard non 4WD cars for 25 years and never had a puncture!
Is there something delicate about the Jimny tyres or is this just bad luck?
Cheers

Even with standard highway terrain tyres you shouldn’t get that many punctures.  Do you know what is causing them, has the garage found anything in your tyre?  If there is nothing in the tyre, perhaps it is the rims or valves, is it always the same tyre or across all four?. Do you have TPMS, perhaps this is leaking?

 I ran around for 18 months on Bridgestone H/T no problem at all.

Thanks for all your helpful replies. My wife has been driving it (hence the economy!) but I understand it was sharp stones piercing the sidewalls. I think the rims and valves are OK. What I did notice was the tyre fitters had inflated the repaired tyre well above the recommended pressure last time it was in there. I do find it odd however that I can drive up and down that forest road in an old Golf and Kia Picanto with ordinary road tyres and never get a puncture yet the Jimny attracts them like a magnet. No sexist comments now....!

45 mpg is seriously good. I manage 42 and feel pretty smug about it.

Sidewall damage is normally a death sentence. A tyre fitter would legally scrap it.

Over inflation won’t help and could make the tyres more susceptible to punctures.  If it is side wall damage, remember the Jimny tyres are relatively narrow (205x70) and if the gravel is deep or rutted then the Jimny tyres could be sinking further in to the gravel then your Golf or Piconto and make side wall damage more likely.

if that is the case, 215 tyres with stronger side walls might be the answer?
