Differences:Is there a big difference? Which one looks better?
I went from 17"s on my 2012 Focus SE to 18's on my new Focus ST
The 17s were smooth and decent handling.
No problems with them at all.
the 18's are razor sharp handling and a lot harsher ride on poor roads. On good roads they are also smooth riding.
As mentioned 18's are heavier and more expensive, and 18" tires are more expensive, with a smaller selection of brands, sizes.
18's are easier to have bent wheels and blown tires. And unless you pay a lot of attention to tire pressures, are a lot easier to run too low and damage them.
Higher probability to hydroplane at lower speeds due to a wider contact patch with very sharp corner which doesn't evacuate water as well.No one has mentioned the extra safety provided by the wider 18's. Significantly shorter stopping distance and greater roadholding in emergency maneuvers. Safer for the kiddies in the car.
I can't post Consumer Reports ratings summaries, but looking at the top 10 summer tires vs the top 10 "performance all-seasons", the advantages of summers are crystal clear.Higher probability to hydroplane at lower speeds due to a wider contact patch with very sharp corner which doesn't evacuate water as well.
Also shorter stiffer sidewalls can be damaged easier by road debris and would be scary at hwy speeds.
Why do autoxers generally go to a smaller tire package vs their larger street set? In most cases weight which really would create a longer stopping distance.
So,point us to some links for to prove this on like cars,just curious since I've read conflicting facts. 18"s do look much better.

Summary of the summers (including the Michelin Pilots and Goodyear Eagles):
Dry braking: All excellent
Wet braking: All but one excellent
Handling: half excellent, half very good
Hydroplaning: all excellent
Summary of the "performance all seasons" including Continental PureContact and Michelin Primacy):
Dry braking: All very good
Wet braking: half excellent, half very good
Handling: half very good, half good
Hydroplaning: half very good, half good
The summers have a clear advantage in every category.
And here are some tidbits from tirerack.com:
I often hear customers say, "It rains a lot where I live, so I need to have an all-season tire." While the name all-season implies that a tire might be the best tire for every season, the reality is that the compound and tread pattern of an all-season tire is actually a compromise between wet, dry and snow capability. Each of these conditions have different requirements, so an all-season tire actually gives away some wet and dry traction to gain light snow traction. Summer tires are the ultimate wet weather performers. They have sticky compounds to grip wet pavement and tread patterns designed to let water flow through and away from the contact patch. The current class leaders in wet and overall traction are the Michelin Pilot Super Sport and Bridgestone Potenza S-04. - See more at: http://blog.tirerack.com/blog/bens-blog/best-tires-for-rain#sthash.Cljv8uqk.dpuf
A summer tire, like the Bridgestone RE760 Sport, will perform better in dry road cornering and braking than an all-season tire. Summer tires also perform well in the rain; wet traction isn’t an exclusive all-season characteristic. Because it rains in summer, summer tires are made to be quite capable in the wet.
