The question of benefits, pros/cons of large rims and tyres was posed to the previous owner of my VZ wagon, a CFA station in country Victoria. Apparently they spent a cool fortune at trade-over putting 17" rims and CORSA 235/ tyres on. These fat, low profile monsters on PDW rims certainly injected some 'oomph', look-wise, but as other posts have observed, a harsher ride results, but with fantastic tactile feel for the road. So bad was it as we bounced over the moguls that after 2 rides my sister came down with appendicitis.
Personally I am not troubled by the sharp feedback from these tyres, or the bumps, and being involved in bushwalking and travelling on remote roads, well, this car isn't a good choice for that, so I go in my friend's company-provided OMEGA — not half as sexy to look at (the car I mean!!), but well able to soak up the horrid corros of recent trips.
I'm not a rev-head or a hoon (not this side of 50...). My car (a replacement for a 16-year old Toyota Lexcen wagonwheels) was bought for me by my Mum, who has alzheimers. But none of you guys should mention that to her. :unsure:
