I have a 69 Beetle (long axle) that has porsche pattern drums and JGE Kozmiks (et +30) wheels to go on

Its stock height at the rear. I have some firestone 145's for the front but have no idea what to run on the back as only have experience with short axle cars/tyre combos.

Want it to fill the arch but no idea what size I can get away with
Been thinking a 185/70?

Any thoughts appreciated

Round ones. In black. Easy. Cheesy

Tricky bit is that different makes of tyre have different sidewall shapes. I had some Avon 165s on my Ghia many years ago on MWS 8spokes and the sidewalls had a lovely bulge that looked great but was only mm from the arch. My orange 70 had Michelin ZX 165s on 5.5J Sprintstars but the offset was funky so the filled the arch, whereas the Anthracite 70/72 I did for my cousin had 185/65s (cant remember the make) on more MWS 8spokes and the tucked in nicer. Not tall enough tho, a 185/70 would have been better but the sidewall might have bulged more. I'll get off my phone and onto my laptop and see if i can find some pictures.

The grey one:


Can't find any other pics of the orange one - think I lost them on an old computer, and I'm pretty sure all my Ghia pictures were on there too.

But then the close ratio box will go in, then the oval motor etc and I have a car I already have!!

Ted, love your car. Just not sure 205's will work with the Kozmiks as the offset is not a tucked

Lee, as the Kozmiks are copies of Porsche-fitment wheels they may have a similar offset to Fuchs or Gasburners? The originals were designed for 912s after all. I've got a feeling that IRS is slightly narrower than swingaxle so that may help Ted too.

That's interesting. Always thought you ran short axles from the start
Thanks Ron

When I went to short axles I had to run a 10 mm spacer to get the wheels off the spring plate

Only had the short axles when I bought the rancho box

I like the grey car a lot, what tyre does it run on the front?

Thanks Alex, they were a 155/70, so nearly as tall as a 145 but a little bit wider. Here's another picture which shows that a 185/65 isn't quite tall enough on the back! Cheesy

When I switched my '68 from stock long axles to SAW short race axles, I went with 3.5" backspace on the wheels to fill the fenders/wings, and just clear the spring plates nicely.  Ran 5.5" 4-bolt EMPI Sprintstars on the street and 6" CMS aluminums at the track with 215/65 M&H DOT drag tires.

Is the 155/70 a summer tyre? I only find it in winter tyre options
