TR4/4A 205 70 15 will these work on TR4?

[TR3pilot]

Hi folks,

I came across a set of new Goodyears mounted on 78 spoke chrome wires. The tire size is 205 70 15, will these work on my 63 TR4? I ask because the current wires on her need lots of love and new tires. My plan would be to put the new ones on my TR4 and current wires which are on her on my TR3 if possible at a later date.

Thanks

This site gives a calculator which gives you the rolling diameter of a range of different tires.

205/70s give a rolling radius of 2037mm which gives 790 revs per mile. (1609340/2037) According to the TR4 handbook, the original tires which were 165x15 gave 820 revs per mile. So your 205s will bump your gearing up by about 4%. Could be some clearance issues too.

I think your clearance issue/problem is more likely to be with the rims rather than the tires. What is the width of a 78 spoke rim? Actually, perhaps they are 72 spoke but in any case it is the width that I wonder about.

Also, have you confirmed these wires are for a TR or similar hub? Lots of Jaguars have 72-spoke rims but a very different splined hub.

Thanks all but something else has popped up that's gonna take the $$, here's the ad if they work for anybody else https://losangeles.craigslist.org/wst/ptd/3769449550.html I had an email into the guy to ask those questions but no reply as yet. Will post it here.

At first glance those look like Jaguar wheels -- hub openings are much larger than TRs.

Those are Series 2 (1968-71) Jaguar wire wheels, won't work on a TR.

I have 5.5 wheels with Bridgestone Potenza 195s and they are a perfect size and fit with a nice wide profile.

Me too, but that's because I saw yours.

The best modern tire (IMHO) for the tr4 is the 195/65 15.It gets lots of patch on the pavement
but wont ruin the front wings in a corner.......205 is sometimes OK, if it is a 65 series NOT 70.
