Need some advice. I currently have 225/40R18 on the front of my 993 and they need replacing. Unfortunately there are none in the country (New Zealand) as last shipment was pre-sold. They do have 235's... anyone run 235's on the front of a 993?

235 shouldn't be a problem. if 2wd no issues, if AWD, just check the ratios, but still should work as I have 235/295 on my car with no clearance issues and its lowered to RS +10, i think

I have run 235/265 for years as this tends to be my go to size, many options from a manufacturer perspective and the car's balance is excellent.
Also from a diameter perspective they are identical for those C4 owners.

Yes in most cases about .2 of an inch, and based on the revolution per mile data it equates to a difference of 7 revs per mile, essentially no difference, well < 1%
No real need to adjust alignment or anything when going from 225 to a 235.
