Changed tire size.

Hi all,

I changed the tire size on my Clarity, from 235/45-18 to 245/40-18 (now running Michelin Pilot Alpin PA4) according to " wheel-size " no big change on the O.D. and the rear wheel well has still enough room (5mm on both sides).

My motivations: a much larger selection of brand and model and this giving me a fantastic choice of category; a wider stance on the road, the Clarity drives like a sport car.

I may be affecting the economy, but coming from a previous Ridgeline owner, I do not think that I'll be much penalized.

For the summer, I'm thinking of going on 19"

My next mods, tinting the windows and installing the rear spoiler.

Fantastic car!!

Overall I like what you did here, from a Performance Standpoint the 245/40-18 size is a better choice all things being equal.

BUT: I have no idea why you would have picked a "Performance Winter Snow Tire" unless your plan was to just use this tire as your ~3 or ~4 month dedicated snow tire based on where you live. I know you mentioned that you are "thinking" about a 19" wheel/tire combo for summer use, but if you don't buy into that expensive $$$ purchase, you will be driving on a snow tire all year long. Snow tires (even performance snows) don't do things as well as their performance A/S counterparts, all those sipes that are cut into each tread block makes for lowered handling (mushy feel) & less fuel economy*.

* Michelin rates the Pilot Alipin PA4 tire as a "Green X" Eco tire, but when compared to a performance A/S Eco tire of the same pedigree, the "snow tire" with all of its sipes suffers in the MPG & handling categories.

This is good to know that a different tire size will work with the current 18" rims.

I was thinking of a second set of tires and really wanted the winter performance tires (studless) for mine as I do go up to the mountains for skiing and winter spey fish.

Very good piece of information to have about alternate tire sizes.

Thanks @ClarityGrayGhost !

Hold on, let's look at some facts:

Like I stated, a 245/40-18 works from a "Performance Standpoint", they are shorter in overall diameter (OD).

A Honda OE 235/45-18 tire is 26.3" tall in OD, a 245/40-18 tire is smaller at 25.7", this difference = A Drop In Fuel Economy.
