Mal. One of the things which will dictate whether you fit 15'' or 16'' tyres is the model of cruiser you have. Early 80 series used 15'' chrome rims and later 80 series used 16'' grey rims and all the base models used 16'' split rims. The reason for the increase was so as a larger rotor and caliper assy could be used. If you have a post '95 vehicle and you get a 15'' rim to fit then it's a fluke and grinding the caliper body is illegal. Apart from this, I don't think it matters what you fit so long as the tyre meets the load and speed specs for that car. Overall diameters are also important as they can effect the braking, acceleration and speedo of the car. I'm running 285/75 16 BFGs and endure the above maladies in order to get a little more ground clearance. 16'' tyres are certainly more expensive than 15''. I paid $256 each for mine in June. There are so many tyres available today that you should easily be able to find something. Talk to a tyre expert and do a search of this site.

Mal, Derek, We had an 80 series with the chrome rims, running 31.5x10.5R15's. Fat little fellars, that helped the turbo a lot when you pulled out to pass a triple road train, but didn't like the 200 k's of dirt and gravel to the bitumen, and tyre repair was a regular occurrence. Now have an 80 with the 16" rims, and running BFG AT's in 265/75R16, and repair work is so rare, that it takes me an hour, huffing and puffing, to change one. The biggest drama is getting the tyre to go onto the beads, now use a 16" bike tube, and they go on better. I like the AT's, robust, with just enough lug if you get caught in a storm, and they wear okay as long as there's not too much rock. We did a trip down to Mungerannie, via Birdsville, few years back, took 2 spares plus an extra case, and didn't have flat in about 1800 k's. Thats with 5 of us, camping gear, and 250L of diesel, tyres running at 32 psi. Tyre choices are harder than working out what sort of beer to buy. Catch you later.

Mal, altough it's very tempting to save some money and go to 15'' rims and tyres it is worth remembering that 16'' will give you more ground clearance. Sometimes every little bit helps.
