Thanks D Murphy for the question.
ARB 4x4 Accessories On-Board High Performance 12 Volt Air Compressor,
ARBCKMP12 http://jo.my/1o3yux
With this compressor it will take about 10 minutes to fill up the the tire total air time.
the only thing is you are going to have to stop halfway through each tire to let the compressor cool down.
You might want to take a look at this one ARBCKMTP12 http://jo.my/loasp3.
It will work a lot more efficiently for your tire size.
Thank you
