Does anyone have a photo of a 205/65/15 tyre on a 7J rim?

As above, really. I like my bulgy 225/60/15s but tyre choices are limited and expensive, and the 205s are recommended in the handbook. I'm worried that they'll look wrong and also that I'll lose a bit of progressiveness.

It'll look fine. 7" is a normal size for a 205 tyre.

Although you can have a look here for something similar: http://tyrestretch.com/

yes Tread one inch wider than the rim - that's about right. I'd have thought 225s on a 7 would look a bit strange!

I had a similar quandary recently when deciding what tyres to fit to my beetle, after much internet searching i decided to just go down my local part worn place and got them to fit the size that i thought i would want on the assumption that i would rather "waste" a few quid and get it right rather than go and spend proper money on new ones, turned out to look rubbish in the first size choice, so went back and asked them to swap them for the bigger size.

£20 per Tyre, and they didn't charge me for the one i took back, so £40 for 2 Dunlop SP sport01's in 205/60/15's with 6mm left on each, and i watched them pressure test them and i gave them a good look over before he put them on.

Not a perfect solution, but for the sake of £20 (or so) might be the best way to check for look/fitment

225s on a 7 were standard on mk2 MR2s (maybe not the best example given their reputation, but they looked normal)

Current rolling stock:



Ironically I fitted these for the MOT- the tyres are 22 years old but have more tread than my current metrics, and I wanted to avoid the advisories (The car won't see speeds in excess of 50mph until I've changed them though!)
Thanks for the suggestions so far. I fit/remove my old tyres so if I can find a 205/65/15 on the heap somewhere I'll experiment.
Any comments on the handling 225 vs 205?

I can do a picture of 205 x 50 x 15 on a 7 1/2 " J if that's any use.

GAjon- thanks for the offer, but don't go to any trouble- the 'tyrestretch' link has a few close examples for me to look at.

Both tyres have huge balloon-like sidewalls, so for a given tyre make/model they should have similar feedback. Dry grip will be a bit lower, but should fall off in a nice friendly way. Wet grip depends on the tyres you're using but shouldn't be dramatically different.

I've often swapped between 195s and 175s on my MX5 and it handles much the same, but with lower limits on the narrower tyre. Changing sidewall height might be more dramatic, but in your case the sidewall height is changing less than 2mm.

I changed from 185/70r13 Avon (5.5J rim) to 175/70r13 Yoko (5.5J rim) on my Caterham and the difference was significant. I suppose it must've just been the tyre characteristics rather than the size that made that difference though...

I thought I may have had a set for you, just checked and they're 205/60 R15 from an E36. I do have a set of those wheels on an E32 too, but am sure they're 225/60s too.

Having dabbled with different width/sidewall combinations on E32/34s in the past, I'd say the decrease in sidewall is a much more noticeable change to ride than the additional width does to handling. 205/65 & 225/60 15 vs 225/60 390, there's not much in it (until it gets wet and the Dunlop TDs are pretty crap) and 240/45 415 with TRX GTs make for tighter dry handling/better feeling steering, but the ride goes West and grip in wet or cold conditions is useless, they're horribly noisy too.

Sadly they will not look as good. I used to run 225/55R15's, but the price of them now is silly compared to what they used to be. So I swapped for 205/50R15. They are ok, but look way skidly by comparison. Which is a shame. Think I'll have to make the move to 16" rims in order to be able to buy wider chunkier rubber for sensible money.

According to the 2008 Bridgestone pattern digest, approved rims for 205/65R15 tyres range from 5.5J to 7.5J inclusive, with 6J being recommended.

The car came with 230/55ZR390 metric tyres. The 225s and the 205s are both slightly bigger in diameter so my speedo will become slightly more accurate, if anything. I am trying to avoid significant change in the car though so I'll be sticking to 225/60R15 or 205/65R15.
I'm going to contact the wholesalers and see what tyre options I have in both sizes.
