KUMHO AT52 ROAD VENTURE Suzuki GV pressures

[MarnoK]

Hi All

I am fortunate enough to upgrade the "tekkies" on my 2012 Suzuki GV from a very cheap set of roadies to a set on Kumho AT52's anyone have experience with them? and what pressure would you recommend (on and off-road)?

Thanks!

For what its worth, I have AT51's on my GV and keep them at 2.2bar on road

How have they held up wear wise? are you getting good mileage out of them?

Almost 2 years to the day, and about 30,000km later they look almost new... Majority tar driving though.

What is the tyre size? If you went down to 16" rims with a higher profile and overall larger diameter tyres, the inflation pressures on -and off road will differ from the stock inflation pressure range and it is best to use the inflation pressure guide as per the tyre's OEM specs for that tyre size.

If you are riding on Suzuki stock rims and fitted a stock size replacement AT tyre, then the tyre inflation guide on the inside of the door pillar (or fuel cap) remains relevant. Nothing changes, really. In general terms and without a heavy load in the back or whilst towing; all four tyres should always be inflated at the same pressures for all types of driving. This is probably because the GV is a full-time 4x4 in permanent Hi Range. I used 240kpa (cold) all around for everyday driving. If you are towing or heavily laden, then the rear tyre pressures can be increased to 260-280kpa cold- if you really feel the need I guess?

On my 31" mud terrain Kumho KL71's I could go down below 150kpa (hot tyres) for sand driving, 180kpa (hot tyres) for general gravel roading and I always used 240kpa (cold) for general highway driving. I would suggest possible the same for your Kumhos; 2.4 bar highway, 1.8 bar gravel and 1.5 bar low range work.

I slightly upsized to 235/65 R17, I am going to De Wildt beginning of December to give them a proper test, will start at 1.8 I think and go down to 1.5 if I feel the need.
