Neal and everyone,


1) Will the 245/40/17 increase my revs on the highway (or decrease them)? (I would prefer to decrease my highway revs, if possible.)

2) Also, would it make the speedo inaccurate. If so, by how much at higway speeds?

3) You said that the snow handling would not be as good with the wider tire. (I live in Texas...so, little snow.) But, does the same apply to wet handling? If so, would the difference in width between the 245 and 255 be enough of a difference to detect in everyday wet driving (e.g., driving down the highway at 70mpg and hitting a puddle of watter)?

4) Will the 245/40/17 (in either the ASX or Pirelli Pzero Nero MS) rub anything on my car under any circumstances (for example: taking an as tight-as-possible turn at a VERY high rate of speed)?

[Also, should I reconsider the ASX's, and instead get the Pirelli PZero Nero M&S? I noticed that you guys preferred them in your test....said the stearing was more razor sharp with the pirellis, and that both the wet and dry handing was better. But, all together they'd cost me $150 more than the ASXs. My question: Is there a BIG difference between the handling between the ASXx and Pirellis? A difference that I'll feel in everyday driving or when darting around an exit ramp?]

Thanks!

That size is only half an inch taller than stock, that of which you split in half. I highly doubt you will see any change in RPM's or mileage. Speedo will read exactly the same. The same rules apply for evacuating any kind of debris from the tires path. Snow, ice, rain, Honda Civics etc. But the minimal difference from a 245 to a 255 wont be that much.

Many have had great luck using the 245/40-17 size. Mainly used as a race application size, but should still work for a street based tire. The ASX isn't a bad bang for the buck, but the better overall performer is Pirelli's Nero M&S. The ASX will be less responsive in handling compared to the Pirelli, but would tackle snow better and last longer. The Pirelli works well in light to moderate snow climates and would be a better performance based tire on the clear days.

Thanks Neal. I'm now sold on the P Zeros. But, the jury is still out re what size I should get. I've decided to go with the 245s, but I wondering if I should go with a taller tire than the 245/40/17s? would prefer lower revs on the highway, if possible. Could I accomplish that by going with 245/45/17s? (Which would be taller than the 245/40/17s, correct?) If this is the case, then would the 245/45/17s rub any parts of the car under spirited driving conditions? Thanks for bearing with my ignorance! (Size is the last factor I must consider before I buy em) -Chris

red-evo

According to TIRE SIZE CALCULATOR
With the 245/40/17 the section width willbe 9.64" ( 9.25" stock)
overall diameter 24.71" (25.32 Stock)
sidewall height 3.85" (4.16" stock)
radius 12.35" (12.66" stock)
circumference 77.62" (79.54" stock)
revs per mile 841.7 (821.4 stock)
speedometer will be reading 61.4mph and the stock tire 60mph
Hope this will help you

Thanks RedEvo. Based on the results, my rpms will be a little higher on the highway (but not much) with the 245/40/17s.

I might just end up going with the 235/45/17s since one of my goals is lower RPMs (and better gas millage) on the highway.

I will sacrifice some dry handling by not getting the wider 245s, correct? In other words, the 245s will handle (e.g., sharp cornering, etc.) better than the 235s, correct?

What about the 245/45/17s? Is it the consensus that tires of that size will rub on the evo? (several past posts seem to suggest that). Is that the current view?

Thanks!

Were only talking about 1/2" wider from a 235 to a 245, which is 1/4" on either side. The handling increase/decrease between the two sizes will be very minimal if even at all noticeable. I really cant verify if that size will rub or not. The overall diameter doesn't seem too far off from stock so you might be ok.

I'm in the same situation. Can't decide whether to go ahead and get the Pnero Zero M+S or settle with the less expensive kuhmo asx or possibly the falken 512.

Knowing this may help you decide: The pzero nero m/s' seem to be unavailable right now. The kumos are plentiful. My research shows that the komos are the best bang for your buck. If you drive your evo hard all the time OR if you have a large budget you may should track down some pzero neros. However, while the difference between the tires is noticable, it's not significant (based on the posts I've read).....those who have run both should correct me if I'm wrong.

Thanks and yep I'm still deciding. Looks like chances for asx is going up. Or maybe I'll store the car and buy summer tires in the Spring.
