A while back a TEOC club member (another car club - www.teoc.ws) gave me a set of multi-fit split rim 17" alloys to put on my Estima. I still haven't got around to cleaning them up and now I've bought a smarter (or rather more 'blingy') set and had them fitted - new tyres to follow in a month or two. Before I clean up the others I thought they might look ... different on The Old Girl, but I don't know if they'll fit correctly. I've trawled the forum, the workshop manual and also The Shadow Owner's Companion without any indication of the PCD, spigot diameter and offset figures to no avail. Can anyone please let me know what they are? I suppose I could just take a wheel off and measure them, but I've got a lot on at the moment and it's just not convenient.
Fortunately the seating cones for the wheel nuts is the same as for steel wheels and the large screw-in centre boss will cover them. There's also a removable logo in the middle I can change for a RR one that I can make myself to finish them off.
Part of the reason I never got around to fitting them is that two rims have good 225/45x17 tyres and the other two have similar 215/45x17s on them. With the Toyota having permanent 4-wheel drive this would cause wind-up in the transfer box and eventually destroy it. Fortunately my Shadow doesn't have that problem!
All I would then have to do is calibrate my speedo by comparing it to my Sat-Nav's opinion of my actual Vs displayed speed - much as I had to do on the Toyota.
Ta very glad in advance Old Chums and Chumettes.

Surely you have found on this forum that the PCD is 5/159.9

Your question is full of difficulties as the SYs have limited wheel well width above a 235 tyre without modifications. To obtain the rolling height, you need at least a 245.55x17 to be even in range for the gearing. A 245 will only just squeeze into a 1974+ SY or non-Turbo SZ.

What width rims do you want so I may advise the offset ? Whatever the rim width, a 225.45x17 is far too small, and more importantly if the load rating is less than 100 they are not up to the job. You would need a very odd tyre like a 225.65x17 if they exist. If you find an adaptor for the PCD and use 17” rims, then you will probably end up with SUV M+S tyres and a lousy ride.

Ooops! Should have said: She's a '76 Series 1 (SRH 24518).
As I thought. The PCD is patently well outside any of the pre-drilled holes. I know one set is 114.1mm as found on many Toyotas. The alternative set can't be much more. I've got a sneaking feeling that the spigot diameter will be far too small as well, which I estimate at 73.1mm like the ones I've fitted to the Estima. Had it been large enough it would have been a simple task to buy ready made or even have custom spigot rings lathed to fit. A local garage turns them in aluminium for GBP40 a set.
It wasn't a matter of particularly wanting to put alloys on her, just that I have this spare set with passable tyres on them. I know about the weight rating of tyres as the Toyota is a heavyish beastie at 1800 kilos unladen and an empty fuel tank. Add 60 litres of juice, a couple of passengers, some luggage and my mobility scooter and it easily tops 2 tonnes. Most club members fit 100 rated tyres to their buses and a lot of them have alloys of 17" or even larger, although the aspect ratio can get crazily low upsetting the comfort of the ride to a large degree.
Never mind. I'll clean them up and pass them on to someone else who can make use of them.

Ooops for me too. Suzukis have used the 5/159.9 PCD on SUVs since the 1970s ! I have a set of specials on my 1954 R-Type which has the same PCD as all MkVI through SZ cars by the way. Although it didnt't help much when I had the wheels made in 1980, I did find it interesting that Suzis of all brands share the PCD with Crewe. It may just help you though, Jan.

I'll keep my eyes peeled for a set of Suzuki alloys then. Whether I'll actually bother or not would depend on finances at the time as The Old Girl is well on her way to needing a full respray. The only quote I've had so far is in excess of GBP3K, although that's from a well respected specialist body repairer and resprayer.

Thanks again.
