225/40/18

[Mr Big]

Is anyone running a beam axle bug with these sizes? I have mocked the front of my bug up with 225/40 R18's but they are seriously tight even with the shock towers trimmed.

I am considering the following:
205/40R18 popular enough size but only in runflats
215/35R18 popular and cheap for an 18" tyre
205/35R18 very difficult to get, but plenty of clearance.

Any opinions? I also need to decide on what brand of tyres to go with.

I want them to be very grippy, so I'm thinking of Yokohama Parada Spec2's. Any alternatives to consider?
