Thanks!


205/50/16 will fit but they're change how the car handles as the Plus rim is a 7.5j and the 205 was designed to fit the standard turbo 7j width.

Plenty of 225 available on demon Tweaks.

Ar...I thought Plus wheel and standard wheel were of the size width (was referring to Useful Info), and now for 7.5J, perhaps I should try harder to look for 225 tyres.

Thanks for the heads up.

From ePER, the Plus wheel is listed as 7J. I took a look at Yahoo Auction in Japan, there's a listing of Plus wheel, in which the pic shown is 7J as well. Attached pics of ePER and Yahoo Auction.

https://page.auctions.yahoo.co.jp/jp/auction/r1054040510

Do you think there are two different Plus wheels various in width?

7j for the turbo, 6.5j for the n/a models, any joy with 225 tyres?

Since you said 7.5J, I was thinking 225 would be more adequate wobble so I placed an order for a set of 4 Bridgestone 71RS 225/45/16, which will be shipped from Japan to Hong Kong. Costed me a kidney rofl

Yes it's crazy shipping costs all over the globe at the moment but at least you've found the correct size tyres for your Plus rims, and to be fair Bridgestone aren't too bad and do last in comparison to track compound.

Sorry to bring this up again, I’m changing my wheels and I’m putting the standard L.E wheels back on. The car is on bilstien lowered springs and shocks. I’ve currently got some azev 18s on and it’s bumpy as hell.

My hope with going to standard wheels, is it will improve the ride quality. I just need to know what the best tyre option is for ride quality and looks?

18s are probably 40 profile whereas 16 inch rims are 50 profile, so they'll naturally be softer compared to the 18s regardless of tyre brand

Cheers Jamie

I recently broke a lowered spring and reverted back to standard springs, night and day far more comfortable ride. I can use my ramps again.


I'm an old git & happy with it,most of the time

That was my assumption too. I read somewhere that people were fitting 17” tyres on 16” rims and stretching them so they look better.

Wasn’t sure how it worked. I don’t want to have massive tyres on as in profile, but at the same time I don’t want spinal surgery anytime soon.

I’d rather comfort without too much ill effect to handling.

You can't put a 17" tyre on a 16" diameter wheel as it's too big.

When people talk about tyre stretching they refer to putting a narrow tyre on a wide wheel. An example of that would be trying to fit a 185 section tyre onto something like the turbo wheel that's supposed to have a 205 width fitted.

Unfortunately you need to run with the correct dimension tyre for the car if you're back on 16s. If you don't you have a few risks to deal with. Too narrow a tyre and it might pop off the rim under cornering or shock. A different profile from standard will result in your speedo being inaccurate. You'll affect fuel economy.

Bit of a resurrection:


Does anyone run 215/40/17s these days?

I'm presently running 225/45/17s which were always a tight fit with lowered suspension but now I've had extensive bonnet and bumper restoration I'm not convinced their replacement in position has been as fine-tuned as when FCSS did it, as there is considerable fouling not only cornering but even in a straight line frown

I have a feeling the 40's might be more crashy than my present 45s.....

Don't forget that tyre sizes between different manufacturers are somewhat wishful thinking... although in theory they're all the same, different tread widths, different wall construction and so on can make a difference. Though if you're worried about millimetres here and there, you're on the wrong wheels, Simon laugh

205/50/16 for a 20vt Neil tongue

It appears our friendly Edinburgh roads have just caused a front spring to break so I now have to consider reverting to standard as opposed to lowering springs; this would help the existing 17's somewhat....

Aha! But I fear I'll need to be even more careful avoiding pitfalls...
