15x6J what offset is required for 3000M?
Discussion
TVR t-slots have a 2.5mm -ve offset. I have just replaced the wheels on my car with 16 X 7" pannasport wheels with a 6mm positive offset. These are perfect on the back but require a 3mm spacer on the front. Tyres fitted are 205/55-16 Khumo Ecstas. I get no rubbing on the back at all but on the front I get a very small rubbing when the suspension is fully compressed on full lock on the lip of the wheel arch on the bonnet. I have had to remove about 4mm but it does not show and is not even noticible with the bonnet open. The rim of the alloy wheel just touched on the end of the bolt that holds the ball joint at the top of the vertical link to the upper suspension arm. A grinder solved this.
I do not think I could go any bigger on the front without doing body modifications but could probably go up to 215 or even possibly 225 at the rear. That would mean I could not rotate the tyres at all front back or side to side (as they are directional).
Several other M's have Pannasports with zero offsets and find they work OK. The 6mm positive offset only became available last year from Pannasport. There were surprisingly few wheels in the size I wanted that would fit on the TVR
Mine is a 1978 5000 M
Hope this helps

5000M? guessing thats a rover V8 then?
did you do it yourself and was it worth all the effort?
I saw John's car at Woodwork last year and very nice it was too! (except for the colour - sorry John)
Are you looking to sell a set of wheels then Colin? Drop me an email if you're interested. I would even consider taking them in part ex against my MGF Cup race car if you want to increase your collection! Has to go to make room for the 3000M rebuild. Would look right stood next to the Tuscan - proper factory built racers of the same era... ish.

A friend of mine did this four years ago and bought Image wheels in the end. He went for 16x7 with zero offset and had the bolt rubbing problem that you described so he fitted a 3mm spacer on the front but I do not think that it is necessary for a 6" rim although 30 is too far out IMHO. I would now opt for 16x7 with a -7mm ET. He runs 205/55/16 all round at present but has run 225/50/16 at the rear with no problems.

Seriously though, if you do get stuck for any bits, let me know what you need.

On that note I know of a supplier for spacers (1 1/4inch) which would get around that problem, normally I would not want to space a wheel that far due to the additional load on the bearings, BUT as the wheel would only stick out as far as the original would it present any problems?
Thanks again

Hmmm, yes there would be problems with the load on both the bearings and the wheel studs. The Ferrari people seem to get away with it but I wouldn't like to recommend such large spacers. The geometry should be ok with 195/65/15s all round.
If your using a 3mm spacer and longer bolts with an offset of +6mm, will it not be the same as +9mm offset.
also the disk itself acts as a spacer from the hub!!!
think about it. plus this is a rwd car with alot less speed weight and power than a Ferrari.
also what PCD is the tvr 1600m

Maybe I should have read this before I went out but I do not know what you are trying to say.

IF THE 3000M IS 95.25 mm PCD
AND THE 1600M IS 114.3 mm PCD,
did they make two types of t-slot alloys?
No, only one type of T-slot for Ms Its the 4.5" TR6 or 114.3mm. I should have made my previous answer clearer - the 1600M has the same wheels as the 3000M and both have the same 4.5", or 114.3mm PCD. Datsun 240/260/280 and some SAABs have the same PCD.

The Volvo s40 range has the same PCD....also the s40 space saver works great allowing the bonnet to be lowered to the right position and also its lighter by a few pounds...
A 3mm spacer used with a wheel with a 6mm positive offset gives the equivalent of a 3mm positive offset. The easiest way to remember this is that a spacer cancals out positive offset. Most of the tyre websites have pictures that show which way offsets go. www.talontire.com/glossary.html#wheel
I recomend trying to use wheels with the same offset front and back if they are the same rim width just so you cannot get mixed up when buying new tyres or just doing work on the car

Although a list would be very nice most of us only have experience of what we have done to out own cars, and just because it fits on one M does not mean it will fit another. One reason for this is that the rear body is not always centralised on the chassis.....and no two bonnets are located in exactly the same place even if they are dimensionally the same.
In my posting you have the maximum size of wheel and tire that I could fit onto mine which should give you a very good idea of what will fit on any M. It is certainly more data than I had when I started working out what would fit.
