i am looking at fitting split rims to my 80 series , question how will it handle with the slimer tyres. [ the current tyres are 31x10.5x15.] i have heavy duty springs and a 180lt tank plus rear wheel carrier fridge ect .we also tow a cormal off rd van. any ideas on tyre choice ,should i go to 16in.the main reason when we leave the van and go off rd split rims are a better choise (so they say) safe driveing mal.

I'm only guessing but I reckon there'd be more chance of running into someone with spare 16" split available than a 15" if you found yourself in the undesirable situation where you needed to borrow one. Actually I've never seen a 15" split but i'm sure they're available

Mal
Last year, I did exactly what you're planning to do.

I bought 16" splits second hand with tyres fitted. I paid $500 for a set of 4 and $200 for another set of 5 rims (4 tyres). I picked the best rims and sold what I didn't need. Ended up with a set of 7 Dunlop Road Grippers - 5 on rims and 2 spare cases. Also have 2 odd tyres - both as new (Dunlop Super Gripper, and Bridgestone Dueller A/T)

Pressure should be much higher at rated loads. I run Front: 50 psi and Back: 40 psi.

Pro's
Skinnys are much better on outback roads and in mud.
Lower enginge revs at crusing speed (2600 rpm at 100 km/hr).
More resistant to puncture / staking.
Ride - much the same as fats.
Easiest Tyre to get in the outback is 7.5R16.
Easiest rims to change by yourself with very little equipment needed and not hard yakka like tubeless.(bead-breaker, tyre levers, pump, pair of boots)

Con's
Speed-o-meter reads low about 4%.
Skinnys are not good in soft sand.
Skinnys are not as good for cornering - more body roll.
Skinnies are more inclined to skid on wet bitumen (IMHO)

Hope this helps.

Hi all.

I am sorry Gordon but I really can not see the logic behind your claims against skinny rims.

1. Speedo.... here I can not comment.

2. Not as good in soft sand....... Skinnies lay down a longer foot print as opposed to and overall width which creates a larger bow wave and hence the need for more horse power to drive the vehicle.

3. Skinnies are not as good for cornering... Here I think you have missed the boat altogether. The Australian Design Rule. If a wheel adversely effects the handling it is not accepted.

4. Skinnies are more inclined to skid on wet bitumen.... Again I think you have missed the boat. Wider tyres cover a larger area (foot print) than a skinny, hence the total weight of the vehicle is spread over a larger area hence less weight per square inch pressure on the road, think about it.

I do not want to make a bun fight over this but I think you gave bad advice here. Fatties look very nice, but if they were that much better and that much more efficient and that much more safer, then can you please tell me why the military uses skinny rims and why the State Emergency Services use skinny rims and why the Police use skinny rims and why the fire services use skinny rims.

Need I go on?

Regards

An addendum.
The effects of skinny rims on body role.....I do not know where you got this from but all that I have been told and read in various bulletins attribute body roll to the suspension.

Sorry about the omission from my original response.

Go for it Mal, the cheese slice is an excellent outback touring tyre, you can carry a tyre with tube and band on the roofrack semi pumped up ready to mount to a rim, or as i did last trip, put a tube under the seat should you get a puncture.
I did on the main street of Tibbaburra, and the nearest mechanic was 300kms away. Fixed it myself in the caravan park.
To answer your questions, they handle good and are larger in diameter than the 10r, so better height and economy from less rolling resistance.
If you buy a set, get some in good condition without rust inside the rims, as the tubes will puncture when it flakes off. Saw a set on ebay and another on sold.com yesterday.
If you can, get 235x85x16 Dunlop adventurer tyres, recommemded to me at Windham as being the only tyre the police use up there.

Split rims and 7.50 tyres are not what the average person would call a 'handling' tyre when refering to tarmac and normal driving conditions as used in the Urban environment ... however in the 'bush' i.e. dirt roads and gravel tracks etc they are the generally accepted standard tyre .... handling means something else in these conditions.. and a 235 -85-16 tyre is a wide / larger foot print version of this tyre... If u are hard up and desperate I have a few 16 x 5.5 Toyo rims to be collected by first person to put their hand up !

Main problem I've seen with splits is the tube fatigue and splits in the tubes. Its hard to get good tubes these days.

Your other option is to get a set of Prado 16x6 or 16x7 rims and fit tubeless 235/85R16 tyres.

Also, the load ratings on your 235R16s are much higher (stronger tyre) than the 10R15's you've been used to.

Suggest you search for Michelin tubes (7.50 x 16 ) they are regarded in the trade as the best... and you will not get them everywhere ! Local Tyrepower man has mine !...i'm in Sydney ..
