My 1986 90 currently has Rostyle wheels fitted with 235/85x16 Colway AT tyres. One of the Colways is more worn than the others (they have about 6mm of tread left). The spare is an 8-spoke, and its tyre is a piece of worn crap. I also have a 5th Rostyle wheel with the wrong size tyre on it.

Eventually, I'd like to replace everythnig, probably to Wolf wheels and good quality AT tyres. I'm happy with the 235/85x16 size. I don't have the cash to do all of this right now, but I would like to put a decent tyre on the spare, and sort out the worn Colway. Also, there is a set of 4 Wolfs near me in very good condition, which I'm thinking of buying. I'd appreciate comments on my plan for an interim change...

Get 2 new AT tyres.
Use one to replace the worn Colway, and the other to replace the wrong-size tyre on the 5th Rostyle.
Put the two wheels with the new tyres on front or rear axle, and use the part-worn Colway that comes off as the spare.
Result: 5 Rostyles, 2 with new AT tyres, other 3 with part-worn Colways.
Change out remaining Colways to same new ATs in the spring.

If this is viable, then what would be suitable tyres to buy? On the one hand, remoulds like Insa Turbos are cheaper, but do they have the mileage of the quality tyres? Insa Turbos seem to come in at about 70 quid or so, but Grabber AT2s are 100 quid from Camskill. BFGs are a fair bit more expensive again - does the extra cost translate into more mileage compared to the Grabbers?

Second idea is similar to the above, but involves changing to Wolf wheels...

Again, buy two tyres, get them fitted to two Wolf wheels, and replace the Rostyle/Colway combo on one axle.
Surplus part-worn Colway becomes the spare.
Next year, look for a 5th Wolf, and add another three new tyres.
Result: Wolfs all round, all with matching AT tyres.

If I do this, is there likely to be an issue with having Wolfs on one axle, and Rostyles on the other? Am I right in thinking that the Wolfs are half an inch wider than the Rostyles? If I get a flat and have to put the Rostyle/Colway spare on one side of the Wolf axle, is that a desperately bad thing, or fine for a get you home?

Finally, if I do put 2 new tyres on an axle, am I better putting them on the front, on the basis that the improved grip will lead to oversteer if I get a slide on the road?

Short version...

90 has Rostyles, 3 part-worn Colways, 1 very worn Colway (remould AT), spare tyre is bag of ****e.

Want to fit 2 new ATs for now, 3 more in spring. Also thinking of changing to Wolf wheels.

Tyres - not sure whether to buy remoulds like Insa Turbos (70-80 quid), or something like Grabber AT2 (100 quid), or BFG (130-150 quid). Sizable cost difference, but does it match up with mileage?

Wheels - okay to fit 2 Wolf with new tyres now on one axle, with Rostyles on other axle?
 
Why dont you just buy a new set of tyres & rims? That is one long winded question leading nowhere. PS. I thort my answer was good. Straight to the point. Thank you.
 
don't swap wheels around it's illegal rto have different size tyres on same axles so all tyres will need to be same anyway.

just buy a set of five matching rims and tyres simples!!
 
I don't have 600-odd quid to buy 5 tyres and rims right now, but I do want to change the spare to something decent, and replace the more worn Colway. The other three Colways have a few months left in them, and can be changed in the sprnig. Just now, I can manage 300 to get two Grabber AT2s and the 4 locally available Wolfs, and then another 300-odd on 3 more tyres and a 5th Wolf in the spring.

Both old and new tyres will be the same size - 235/85/16. (Aside from the new ones probably being slightly larger diameter due to having new tread.) The only other size oddity I can think of is the width of Rostyles and Wolfs, which I think are 6" and 6.5" respectively (but not sure). The only time there would be a Rostyle and Wolf on the same axle would be if I got a puncture.

What's the deal with using tubes with tubless tyres? Can I do that if it turns out that the Wolfs are the tube type? (Will find out which they are tomorrow.)
 
Yer off yer head mate. You dont need £600 - odd to buy tyres & rims. Forget the mix & match carry on. And using tubes in tubeless tyres... How daft can you get? Dont be stupid. You're not only putting your own life at risk, but other road users as well. If you cant afford the kit then keep your truck on a SORN till you got the cash. I think I'm pretty sure in saying that most of us save our cash and buy the right thing for the job. You Sir are an idiot for cutting corners. Bout time you got yer head down and scrubbed the deck.
 
Thanks for the flame.

4 Wolfs available locally: 100 quid
5 Grabber AT2 at 100 quid each: 500
Another Wolf: 25-30 quid

I make that 600-odd quid.

got a set of 4 freestye alloys with at's on up for sale?
 
I don't know how to paste & cut & all that ****e, but type in Peter Shepherd Tyres/Rims. He'll get you what you want at a good price. Cost includes fitting/balancing etc.
