If these wheels were 50mm offset, I'd be quite happy. Could put a spacer in the back if I wanted a more "flush" look in the rear. Right now, the rear is almost flush,, a bit inside actually, looks better than stock which is way too much inside. But the front stands a bit out of the fender, and with the aggressive thread pattern on these particular tires, it does give a bit of that off-road look that I don't particularly like myself.
Yup, 205/45-17 is a little on the thin side. But so far no issues, I ran over some serious potholes and over some curbs gently by mistake, and not a scratch yet - these particular tires have a very beefy sidewall protector and the construction of the tire is very sturdy as well - much sturdier than another brand that came with the wheels an which I have disposed off since. A lot of small production cars like Toyota Corolla come with this size tires these days in the "fancier" trim levels.
I run them at low PSI compared to what most Insight owners do - pretty much recommended settings around 32-34psI. That gives a reasonably comfortable ride and in fact better stopping than overinflated tires.
MPG? Hard to tell. The Michelin Pilot Sport AS/3 seem to be easy rolling tires, relatively speaking, but I guess there is a hit of a few MPG. I can still do my usual 50mpg on the highway at lower speeds under 65pmh and in the city all bets are off as it depends mostly on traffic. The car does not feel sluggish and glides well.
Cornering, stopping, and especially wet traction is very good though, much better than the previous similarly specked off-brand tires. That's what I care about, not so much about MPG with these tires.
I might try to find a way to widen the front fenders just a little - both my front fenders are damaged cosmetically from two separate accidents, so I might use this opportunity to have a body shop create a 1cm flare out that should take care of the occasional rubbing. I might also install new shocks with slightly more damping, which should eliminate all but the worst-case rubbing on really bad bumps at high speed. If I just go with traffic, I pretty much don't have rubbing, it happens if I am not careful and drive faster than necessary and get surprised by some unusually deep indentation in the road. Speed bumps and normal road features at the expected speeds are not an issue.
There are 195 wide tires in 17" diameter, but only 2 models that I could find and they are summer tires if I recall right, from Yokohama https://www.tirerack.com/tires/tires...omCompare1=yes
They are 195/45-17 tires, which are about 4mm lower profile than 205/45-17 tires and 10mm narrower, so they should have absolutely on rubbing issues on these RPF1 wheels in my estimation. But I don't want summer tires, so I'll stick with the 205/45-17 for now. I got them at a fairly good price so I'll just wear them off and reassess my options at the next tire change.
It's a pity that the Insight can't take more than 205mm wide tire without issues, because there is very little choice in narrow tires in 17" diameter. Going down in wheel diameter to 15 or 16" opens-up considerably more options - they just don't make narrow 17" and bigger diameter tires...
