15" or 16", Canning & Kimberley trip ??

Have 33 x 15 x 10.5 BFG muddies and am on the Duncan, Gibb or Canning every week. Staked the first one in four years on a graded bore line about three weeks ago.

Having 15 or 16 inch tyres wouldn't make any difference - other than probably to your wallet.

I've travelled the western deserts many times, including the CSR and many cross country trips over the last 15 plus years on BFG AT 15s. Others with me have had 16s. There wasn’t any difference in puncture rates or clearance problems.

In my opinion stick with what you have and spend your money on a high quality tyre pump or Poly Airs if you don't already have them. You will appreciate both on a trip on the CSR.

Rag,

16" tyres are a lot more accessible and tougher than 15".

If you still have the 16" rims put some new rubber on them and have a good trip.

I'd Probably go the 16's. Just remember that the wider the tyre (I run 28575R16's on the GU), the harder they are to replace as you get further away from the Larger regional centres. For example, a tyre of that size was impossible to source in Alice Springs.

Cheers Mick

G,day Rag, Spent 8 weeks in the Kimberley June / July 2008. Did the gibb , mitchell falls, bungles, tanimi, ect ect towing our camper trailer with 2 kids. Started and finished in Vic.. 13800 kms . Running 32x11.5 r15 bf mud terrains on GQ and 750 16,s on split rims on trailer. Had great trip without a flat tyre. Hope this helps. More info email me.

Hi Rag
I used my 15" Bridgstone Desert Duellers for 10 years on my 60 series across the top end (Gulf to the Kimberlys) and while I got the odd puncture and staked tyres, they were on a par with mates using 16" tyres.
Stick with what you have.

Cheers Rod

Just have a look at the load ratings of the tyres.
Usually "flotation" 15inch have much lower ratings than LT 16inch.
The BFG site has this info and you should compare it with the minimum ratings on the tyre placard on the car
