100 series spare wheel

RWC seems easier than a bashplate. Probably cheaper too.

If you're worried that a rock would hit it adding a bashplate is not going to make that much difference ... you're still going to be dragging ya butt.

There seems to be some cheaper RWC's getting around at the moment for all those who have had LPG fitted. The carriers bolt over the exisitng bumper and are not the kaymar style expesive bumper replacement. You could check out a gas fitter for a supplier or price.

I had the same concern and now carry a "splitty" underneath. I carry the original spare separately if the trip warrants it. Also the spare on my camper trailer is interchangeable with the LC.

Spliney

We have an 80 series and carry a 7 inch rim fitted with a 235/85 16 BFG A/T. It lies above a line from the diff to the towbar and does not get hit. However we do have a 70 mm lift and Polyairs but it still did not hit even before the polyairs. It has the same rolling circumference as the tyres you already have.

Have you thought about putting a false floor in the back? I did when I had mine converted to LPG. Tools and other junk go under there as well. Much cheeeeeeper than a RWC

Ring around your local Toyota dealerships and wheel sellers, the base model LC comes with split rims and are often disguared on purchase, these are a nice narrow rim and sit up well under the body. The are often on ebay too for about $10 each.

All I usually do is take the spare off and chuck it in the back when we go out for the day, up on the roof rack for longer trips. A rock damaged $280 lesson makes sure it never stays underneath when going off road.

If you get a 50mm+ lift it will lessen the risk of scraping the spare.

The above comments are goood. Plus the cost of any serious bash protection is probably the cost of a new tyre. So the chances of it happening.... why bother??
