Tire trailer - 225/45 on 8 vs 225/45 on 9

That's my trailer loaded with the current wheels/tires - 225/45 on 8" 6ul's. As you can see (or maybe you can't) there's a sidewall bulge which prevents the wheels from contacting each other while loaded on the trailer.

Because you all suck, I have been convinced of the superiority of the 9" wheel and I have a set on the way, which will be wearing 225/45 RS3 rubber. 140 treadwear will allow me to stay in the street tire class of the local PCA's autocrosses, which I have decided to take a crack at.

My question is, when I load the 9" wheels on the trailer this way, will I need to put something between them to avoid scratch/rash damage etc?

If you're worried about that, stuff some cardboard between them

or the tampons

You borrowed my last box, I'm all out. Obviously the answer to whether I need to do this will become apparent to me when I load them onto the trailer for the first time. There was a gentlemen at an event earlier this year running 205 rcomps on 8's, and he had made spacers out of rubber mudflaps or some such material.

Nothing wrong with wanting to keep your equipment in good shape. Anything that vibrates against anything else will eventually cause wear issues. Right, Vlad? This is why you stock up on the soothing ointments.

I returned your tampons baby, they were way too big for me.
And the soothing ointments are to prevent scratches from your dingleberies:giggle:

don't worry about your wheels, the inner rim will machine itself on the control arm anyways :)

also just do this

On 9s with 225 NT-01s the inboard sides of the wheels touch. The two center wheels touch because I load them face to face on the outsides. I don't care about chipping-up the inboard side of the wheels.

225/45 RS3's on 9's will touch if there is any amount of force applied. For example I can stack my wheels without them touching if I'm careful. However if I take one of my wheels and flop it on its side from 1" above the floor the rim will hit the ground.
