Who is Cy

Hi, I'm Cy Chowattukunnel (in old country language, my last name means he who knows all about tires). I'm entering my 10th year at the Tire Rack.  So far it's been a great ride. I've enjoyed working with drivers across the country and around the world.

Your recent article on the late model Dodge Ram wheels has an error. The standard size for alloy 17" wheels is 17X8, not 17X7. Thanks, Jeff

Dodge used both 17x7 and 17x8 wheels, we added this additional information to that post.
Thank you.

We now have a 2012 MK 6 Golf R. It is my wife's Company car. We do an 80 mile commute. As you know,car has the Dunlop AS in 225/40 18. My other car (1998 Black Passat) has 225/45 17 Michelin Pilot Sport AS Plus, and I like them very much, I believe I can feel a little less slip angle and I would say they are the best tires we have had on this old car.

We do not plan to do any track days or wild cornering with the R. It gets about 25 MPG short shifting much of the time 2,4,6. It seems geared low to me. I wonder about a lot of possibilities. If the Yoko Green tire made of oranges could really save me some fuel mileage and if they had some grip, maybe that would be a good idea for fast cruising, or is this thinking bogus. I do not think we want a dedicated summer tire. Could get the Pilot Sport AS, or save money and get the Conti AS, do not like Conti, but you guys say they are very good. What about trying to go to a taller tire, like a 45 section (or, to explore fuel mileage, how tall could you go, and then there is all that weight like a big fywheel). Perhaps a 235/40-18 Pilot Sport A/S. I believe it weighs the same as the 225 and is taller, and may even last longer because it is more tire. I do believe that wider tires have poorer Aero Cd, and can be heavier, and can have more rolling resistance, and can affeat steering and ride feeling every imperfection on the road. We can stay with stock size, or try to get better fuel economy and even ride. We will let the next owner be the one to take it to the track, I have an old Lotus 7 for the track.

Thanks Cy.

Hi Gerry,

For your emphasis on efficiency and for a tire doesn't overly compromise steering response and overall handling I would look at a lightweight 225/40-18 tire like the Pirelli Pzero Nero AS see:


Taller sizes will hurt efficiency because of poorer aerodynamics. Taller sizes will also raise the center of gravity slightly negatively effecting how sporty the car feels.

The 225/40-18 Pirelli Pzero Nero A/S linked above weighs about 2 lbs less then 225/40-18 Michelin Pilot Sport A/S so that couple with experimenting with air pressures 3-5 lbs above the 38 front&back factory pressure should help with efficiency.

Hi, I have a 09 impala with a high speed vibration that happens only after about 20-30 min at high speed in warm weather, this is since the car was new every thing has been checked out by the chevy dealer and is ok.
. The tries have been balanced twice/w a hunter roadforce balancer /w a litte improvement. Chevy customer service says the car was designed this way??? My question does tire rack sell a good allseason tire that doesn't vibrate at high speed without needing to be roadforce balanced?

Clarence, based on your summary the vibration doesn't appear to be caused by a tire or wheel issue so I'd recommend having your Chevy dealer continue to trouble-shoot so they can find the root cause.

Is it posible to move up from 215/65/16 to a larger size on the stock wheels of a 2005 CRV?
Tuesday, September 24, 2013 by cy

Jim, 225/60-16 will fit on your Original Equipment 16x6.5 wheels without rubbing. 235/60-16 will fit on your wheels but we consider it to be a custom size because may require rear fender liner modification. Thanks. Cy.

Cy,now that I have the Ecopias for the '05 CRV what is the correct rotation pattern?
Thanks for your valuable advice.

Jim, your CRV's all-wheel-drive system only engages the rear wheels when needed so the front-wheel drive rotation pattern listed here is optimal for most CRV drivers:


Thanks. Cy.

2010 Honda Fit Sport ... What is the next size up from standard?
Tuesday, October 15, 2013 by cy

Hi Jim, nice to hear from you again, 205/50-16 is the alternative size - see the blog about using this size here:


There some tire recommendations in the blog itself and the comments. Thanks. Cy

Hello, I purchased the General Grabber HTS60 (235 65 17) for my 2008 Volvo xc90 AWD 3.2. I'm having a lot of issues with cornering on the highway. any time I go over 60 mph and try to take a corner, the car feels like it is on ice and wants to take a 360 degree turn. I have to slow down and try to keep it straight in the corner. I had the suspension and steering checked, no issues. Then finally someone said that it might be the soft ribbed looking sidewalls. They believe that during the cornering, the tires are flexing out under the weight of the heavier xc90 and the tires are riding on the sidewalls. The wear pattern are on the edge where the treads meets the sidewall. I read somewhere else about increasing pressure from 36 psi to 41 psi. I ran this by a couple mechanic and they said I should always stay with the recommended pressure. More pressure will lead to less center wear, but less grip and it will also affect the suspension. Is this correct, or will more pressure counter-act the soft sidewalls? Thanks J

It sounds like you're a very spirited driver who's switched over from a higher performance tire. I'm surprised that you're getting shoulder wear in the apparently short time you've had the new tires but harder driving can lead to excessive shoulder wear. If you have noticeable shoulder wear there is no innate harm in experimenting with running 41 psi instead of 36 psi. Running higher air pressure can lead to excessive center wear but a 5 psi difference isn't usually enough for someone who has shoulder wear. There will always be trade-offs in steering response, cornering stability, acceleration grip, braking grip and cornering grip when you experiment with air pressure. Experiment and see what you like.
Thanks. Cy.

Cy, can I really downsize for winter tires and rims on a 16 Camaro SS? I'm getting mixed reports from installers and dealers. Some wont even sell downsize to me. Thanks for your help.

Thank you for your inquiry. Wheel clearance will vary depending on diameter, offset, width, spoke thickness and spoke curvature. Once you click enter the Winter/Snow Tire & Wheel Packages here:


The only wheels you’ll see are wheels we’ve checked to confirm fit.

So yes, you can downsize as long as you're selecting wheel from the above link.
