quick update on the new Toyo Proxes S/Ts...

so far so good... i swapped out the 18s to 214 20s w/Toyos and on the way home from the dealer i immediately noticed better traction and cornering ability (obviously because i went from narrow 18s to wider 20s)
but the tires held up great with no slippage...

in the rain it performed as expected... very good confidence inspiring traction...

i did feel a very slight slip on the right front wheel while taking a hard corner on an entrance ramp.. not a scary slip but a slight chirp/skip as i was making the turn.... (like i had great traction but it was hitting its limits)

as for bumps...no significant difference from the 18 run-flats that i thought were horribly stiff....

so in summary... the tires offer better traction, gives the vehicle a much more meaner appearance, and is no better/worse in day to day pot hole reaction than the stock 18s....

Of course, I'll continue to swap to other brands as the need arises...
my next set will be the michelin latitude Pros just for comparison...
