New Hilux

Unless one asks questions we never learn or be pointed off in the right direction to research and learn. Thanks for your pointers. If the rolling diameters are to same because of the tyre profile then rough road performance is not going to be effected except for the reasons given by other forumites below. If the rolling diameter is less because the rim is 1" smaller the wheel will tend to fall into holes rather than bridge them. We had small cars and large cars in the family and I have always noticed how the larger cars with their larger wheels are smoother on dirt roads.
It will be interesting to see what the salespersons say about the change. They might surprise me with educated answers, then they might bullbleepme because they do not really understand either.
If I like the new Hilux it looks like I will have a set of good Coopers for sale.
Thanks for taking the trouble to reply.

Cheers. See my comments to Greg.

Hello - apparently with a bit of angle grinding the older 16" rims will fit.
Understand the benefits of lower profile tyres but really would 1" make a noticable difference when other variables also come into play (road conditions, vehicle weight, tyre pressures, speed, tyre brand, driver experience)? There may be a theoretical advantage but I doubt the average Joe (me) would notice. Also, as has been discussed before on other posts, the length of the tyre footprint is far more important than width so the abilty of a tyre to "bag" sideways is not as important as overall tyre diameter and its ability to "bag" forwards/backwards...again theoretically the larger rim/lower profile tyres have a disadvantage...again doubt if it would make noticable difference considering other possible variables (when comparing 16" to 17"). My conclusion on 17" rims - could just be a marketing ploy for 4WD's and in reality doesnt matter which you choose/are made to use.

Cheers, see my comments to Greg above.

Too far to travel mate, I live in Sydney. Anyway I live on the north shore, why would I travel to see one? I just ring up and they bring one around to my place! Someone on the forum said they looked "orrible". If it is bigger than the old one and has 15" rims it will look strange.

Keep trucking mate. (I hope you are not one of the 80% that are on drugs!!!)
