I tested today all my PU/airless rubber wheels and I would like to give you an idea of my impressions.
Here are the wheels that I tested from 90mm to 120mm
90mm Teamgee
Comfort: 6/10
Grip: 7/10
Range 8/10
TeamGee 105mm rubber wheel
Comfort 6/10
Grip 10/10
Range 3/10
107mm Flywheel
Comfort 8,5/10
Grip 8/10
Range 4,5/10
110mm TB
Comfort 9/10
Grip 9/10
Range 4/10
120mm Foamies
Comfort 9,5/10
Grip 7,5/10
Range 3,5/10
What I didn’t test today but I would rate from my mind is:
Old 97mm 76A Evolve
Comfort 5/10
Grip: 5/10
Range 8/10
New 97mm 76A Evolve
Comfort 7/10
Grip 7/10
Range n/a
Orangutang 85mm 77A blue Caguama
Comfort 6,5
Grip 7
Range n/a
Chunks I had just with 107 Flywheels and 97mm Evolve, but especially on the 107’s a lot.
May favorite wheel is the TB 110mm 74A by just a very small margin over the Foamis. On kart race tracks or slick surfaces I rather go with the TeamGee rubber wheel though. Through hard and loose, dry, rough terrain the Foamies are king. Trough wet, slippery, soft terrain the rubber wheels are best again. For smooth tarmac I prefer the TBs or even smaller wheels like the Cuagamas or 90mm TeamGees.
I never had the opportunity to ride red 100mm Boas though.
Hope I could help
