Would these pass a scrutiny check if I wanted to go hillclimbing?

7'' globes with 235/60/14 Yokies 352 looks like they stick out a bit, nothing ridiculous but the lenghtened arms on the rally car don't help. Just a one off thing won't be changing the rally set up.

A235 tread width tyre on a 7" wide rim, will have the tyre wanting to fold over, unless you run very high PSI.
High PSI will not allow the tyre on that rim to work to optimum.
F these are what you jave, they'll be ok, but look at 38-42 psi.

The main thing is, get out there and just give it a go, you'll have plenty fun, and get to see, and talk to, others and ask them how they set their car up!

Deally, a 205/55 or a 205/60 on the 7" rims allow you to drop pressures to around 24-26, which allows flex in sidewall, and keeps as much tread surface flat on the road surface, though the suspension travel.

Yeah they are big boots i guess I'll have to give it a squirt on the local hills.

Your right on the side walls, when fitting them to the rims I noticed alot flex for what was an expensive tyre

It's a baggy tyre for the rim, but that size was used on many a 7" wide rim on old XB/C falcons and Valiants back in the day.....

And how the hell did you find some Yoki 352's???? I wanted some for my charger and couldn't track any down.

I have nothing useful to add, just came to reminisce about Yoki 352's - ran them for years on my 1600 in the 80's for road use / hillclimbing / even the odd khanacross.

White writing inwards, of course !

Usually 205/60/13 on a 6" rim, went to 225/60/13 on a 6" rim at one point  :o, handling went downhill so back to 205 when the 225's wore out.

Good times  :)

On the old Falcon or Valiant, it was either hotwires, globes or jellybeans, 14x7" on the front 14x8" on the rear and the white lettering to the outside for the 352's if you were baller, Bridgestone SF340's for most or BF Goodrich's if were brave....... ;D
