stretching is also used to stiffen the sidewalls on cheap tyres. drifting = many dead tyres and hence people tend to look at cheaper tyres.

just because you dont do it daoesn't mean it's only wank factor

Rubbish. Stretching doesn't stiffen sidewalls. It detracts from roadholding which enables drifters to loose grip (slide) with less power.

Wah?

That's a lot of stretching.

Unless something is wrong here:

9 in = 228.6 millimetres

so 225's on a 9in would give approx 3.6mm of stretch.

AKA nothing noticeable.

The tread of the tyre is roughly the same of width of the rim, so the sidewalls will be more or less right angled.

9.5 in = 241.3 millimetres

235's on a 9.5 would give 6.3mm stretch, which i believe would just start to get noticeable.

If i've got it wrong let me know.

Go look at a 235/45x17 on an 8" wide rim, and tell me if you think a 225 on a 9" would or wouldn't look stretched.

The advertised width of a tyre (225, 235 etc) is not an exact dimension that you can take to the bank. It's nominal, and in fact it changes depending on what width rim you stick it on.

See attached photo. Tyre on the left is a 255 R comp. Tyre on the right is a 235 road tyre. Reckon there is 20mm difference????

For what it is worth the 235 looks underdone on a 9" tyre.

Like said above, seems to work on paper, but not the way it works.

Can provide photos of a 235/45 on a 9.5, doesn't even sit on the wheel. The lip on both side stick out.

9" doesn't include the lip. It's the inner part of the rim i.e. the amount of tread on the ground.

255mm includes the lip, sidewall construction + the usable tread

why do you want to fit an incorrect tyre size on a given rim? years/months/weeks of engineering had gone into it and people fk it all up by mixing and matching the tyre size.

225 on a 10" wide rim.

    • Sorry to hear your HFM BM57 was faulty,  did you contact HFM I would hope they would be at least grateful for the information if there was some sort of manufacturing fault, you would hope they would be sympathetic even if your item was 2 years old if it had never been fitted. May I ask where it leaked from ?
    • Cats are called Bella, and Donna...  Like that poisonous plant And I remember your 2 monsters, I remember making a little bit of wee when you let them out... LOL I have already installed cat doors into the laundry where their kitty litter is, and the sun room, apart from the cat doors there's not going to be any permanent mounted stuff on the interior walls (interior doors are cheap and easy to replace) I will get a outdoor cat cage thingie once I finish the landscaping out back... https://catnip.com.au/ The only off limit areas are the main bedroom and the gym room....but, currently the cats are curled up in bed, in the main bedroom with the Mrs.....LOL, the off limits for the kittens to the main bedroom lasted about 5 minutes with Jackie I currently only have 1 free standing huge cat tree multiple level scratching post thingie in the lounge room, but, I will be getting another one soon now that I'm happy with the furniture layout in the back room and have a perfect spot for it  
    • All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.
    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
