I've run 26" through to 30" off-road tyres on Subies. There is no doubt that the larger rolling circumference makes easier work of obstacles. No doubt at all. I have also run up to 37" tyres on Landcruisers with similar gains in off-road-ability. Bottom line, run the tallest, narrowest tyre you can. Subarus are very light and even a closed pattern 8.5" tyre will have trouble digging for traction when compared to a 6". The well known problem with a big jump in tyre diametre is gearing. I've managed to keep gearing in check with 4.444:1 diff ratios and lower geared gearsets.Subafury wrote:im sorry guys I did not word the thread or poll correctly, so its inaccurate. It is as andrewt says here. the real question Im asking is "should I put tyres larger than 27 inch on my car and what are the pros/cons".
might as well continue with the current argument about the 6stud and engineering tho but id like more info on offroading and the 29's.
also what sizes are you running.
Personally, I can't see the need to drill 2 extra holes in a 4 stud hub. If I wanted to use a 6 x 150mm PCD rim, I would simply drill 2 extra holes in it and bolt it on. Illegal? For sure. Safe? I wouldn't race on it or put in on a public road but for mild offroading on private land...
The best option for anyone looking for a serious upgrade is obviously the 100% legal Crossbred 5 stud conversion which puts you into modern 4 wheel disc brakes, Liberty front struts and a huge choice of rims from 14" through to 20" and maybe larger.
To answer the "should I put tyres larger than 27 inch on my car", ask yourself if you have trouble driving the terrain you like to drive on with your 27"s. Don't go bigger unless you need to or want to. I seldom need to but I always want to.

Thanks Brumbyrunner, your post has brought up several questions that may help out other less knowledgible people like me plan their mods. What I come away with is planning your mods for the useage of the vehicle. Thanks for your knowledge.brumbyrunner wrote:I've run 26" through to 30" off-road tyres on Subies.

Speaking from a totally personal perspective I disagree with thinner tyres being better on a 4wd for serious work. Wider tyres give you a larger contact patch and a better chance to grip on solid material, especially in soft sand. Thinner tyres have a habit of turning themselves into cutters that cut through the soft material and cut down into it.brumbyrunner wrote: Bottom line, run the tallest, narrowest tyre you can.

A subie is a slightly different case but only because of its weight compared to other 4wds except for maybe a Suzuki Sierra/Holden Drover and even on the little Suzies you are much better of with wider tyres in soft conditions.

Not shooting you down but its the length of the foot print not the width that helps out in sand.Storm wrote:Speaking from a totally personal perspective I disagree with thinner tyres being better on a 4wd for serious work.
