After many years of working at Tire Rack, I find that it can sometimes be easy to take for granted some of the information and concepts that I use on a daily basis. One such concept called plus sizing may be well known in the tire industry, however many consumers aren't familiar with how it works.

The purpose for using lower profile tires in plus sizing is twofold. First, doing so maintains the overall diameter of the Tire & Wheel Package. This is important to keep the accuracy of your odometer, speedometer and other vehicle instrumentations. Second, plus sizing with a lower profile tire often leads to more responsive handling and a better cosmetic appearance.

Notice that while the wheel diameter increases, the tire profile decreases. It's that simple.

You don't have to do the math on your own! Our website fitment specialists already know what size to use on your vehicle.

I cannot speak for a manufacturers vehicle warranty, but the widest size we've used on the 2013 Honda CR-V on the factory 17" wheel is 235/65R17.

The Plus sizing concept in this blog is about using larger diameter wheels. We have not tried taller tires on your OE wheels for this vehicle so I am not sure if that size will fit, sorry.

Each step up in wheel diameter will result in a firmer ride. If ride quality is of utmost importance, stick with 16".

225/45R17 tires will indeed fit on 17X8" wheels.

When going to 16" on a 1998 Chevy Malibu, the correct tire sizes would be either 205/55R16 or 225/50R16. I do not have compatibility information on Chevy original wheels, sorry.

I have 225/65/17 at the moment ,and what is the purpose of spacers?

You can check out the complete list of wheel sizes and styles we carry that fit here :

Driving a 2011 Camry LE with 215/60R16 wheels. Could I put 225/50R17 tires on these? If so, what would the effect be and what would I have to consider? Thanks!

Yes, if you purchase 17" wheels, the 225/50R17 size is recommended. Since this size maintains about the same overall diameter, there would be no negative affects on speedometer/odometer or other vehicle instrumentation.

Those sizes are much too tall for the 2008 Honda Civic. If you plus size to 17", stick with 215/45R17 or 225/45R17.

http://www.tirerack.com/wheels/wtpack.jsp?affiliate=FH8

Plus sizing or minus sizing does not change the overall diameter (total height) of the tires, so clearances would not be changed.

We would recommend size 245/45R17 or 255/45R17 on the 2003 Ford Mustang. These wider and lower profile sizes will ride more firmly but increase handling capability and cornering grip.

We aren't sure if the taller and wider 245/50R17 will fit properly on the 2005 Acura TL. The largest that we have fit with success has been 245/45R17.

Yes, you can indeed use 225/45R17 on your 2013 Subaru Impreza Sport Limited with no problem. This wider size is a common upgrade.

The tire size 225/50R16 will indeed fit the 2003 Chevy Malibu if you find properly fitting 16" wheels.

Thanks

Yes, with properly fitting 17" wheels, you can indeed use tire size 215/45R17 on the 2007 Honda Civic Sedan DX .

215/60R16 is a bit taller than we've tried to fit on a 2006 VW Passat so I am not sure if it will fit without rubbing.

The largest that we have tried on the 2011 Malibu is 235/50R17, so I am not sure if the 245/50R17 would fit.

The largest combination we've run successfully on the 2013 VW Jetta SE would be a 19" wheel with tire size 235/35R19.

225/60R17 is much too tall to fit any year Malibu, sorry.

I can check on this for you. What year is your F150?

My mechanic said it's no problem. Is he correct?

205/70R15 is larger than we have tried on the 2002 Toyota Camry, so we are not sure if that larger size will fit properly.

Yes, you can change all four tires to size 225/75R16 with no problems on the 2008 Ford Escape.

Unfortunately we have not tried to fit tires that are taller than the original 235/55R17 on the body style of Mustang that you own.

215/65R16 is much taller than we can recommend to fit a 2013 Mitsubishi Lancer, sorry.

Unfortunately these cars have different bolt patterns, so wheels are not interchangeable between them.

would you please tell me which wheel/tire size I can downsize to from 255/50r/20. I need winter tires for my 2013 ford explorer. 18 inch wheel maybe??

Thank you,

Joe

You can indeed minus size to 18" or even to 17" on the 2013 Ford Explorer. You can view all of the available options at the 'winter' section of our site here :

Winter Package Shop by vehicle http://www.tirerack.com/snow/changeover.jsp?affiliate=FH8

We've used up to 19" wheels with matching tire sizes that would not affect the speedometer.

I have a 2013 Acura TL SH_AWD. I want to put some aftermarket rims on it and want to go a little bigger than stock. (fatter and larger rear tires) What tire sizes have you put on my specified vehicle tha tlook good? Thank you!!!

We have used a large variety of sizes on this vehicle, all the way up to 20" wheels with 255/35R20.

You can view the complete listing of wheels that will fit in all the sizes here : http://www.tirerack.com/wheels/wtpack.jsp?affiliate=FH8

Yes, 225/45R18 tires can indeed be used on a 2008 Camry with the correct 18" wheels.

You can view the complete list here :

Either size works with no problem, although 195/65R15 is closer in overall diameter and a bit more narrow which would help with snow traction.

I'm unsure about Honda OEM wheel fitments as we do not sell Honda OEM wheels, but we have not found any aftermarket steel wheels that clear the brakes on the Civic EX in 15"

http://www.tirerack.com/wheels/wtpack.jsp?affiliate=FH8

I can check on this for you. What size wheels do you have on your 2003 Mustang?

235/60R18 is much too tall to fit a 2011 Ford Mustang, sorry.

When using 14" wheels on this car, we recommend tire size 175/70R14. 185/65R14 should also work fine.

The tallest 17" size we have fit on the 1997 Subaru Forester without rubbing is 215/55R17.

What model of 2003 Honda Accord is this? An EX?, an LX? V6?

We do not recommend installing tires with a shorter overall diameter due to less load capacity and safety issues.

Thank you.

I do not have cross compatibility information between different models of original wheels, sorry.

Yes, 245/40R18 is a correct Plus one size for the 2008 Honda Accord 4cyl 2 door with 225/50/17.

http://www.tirerack.com/wheels/wtpack.jsp?affiliate=FH8

Yes. Generally speaking the larger the wheel diameter (and thus the lower the tire profile) the firmer the ride will be.

To keep the same overall diameter, check out tire size 225/45R17.

http://www.tirerack.com/wheels/wtpack.jsp?affiliate=FH8#sthash.oT8pXHfH.dpuf

When plus sizing to 18" on the 2003 Toyota Camry we do indeed recommend tire size 225/45R18.

http://www.tirerack.com/wheels/wtpack.jsp?affiliate=FH8

Wheels diameter: 19 Inch

Wheels Width: 8.5 Front and 9.5 Rear

Offsets: 35 Front and 40 Rear

The recommended rim width range of 215/45R17 tires is 7"-8" so this size would not be suggested for 8.5" or 9.5" wheels.

Can I replace my 2012 volts 215/55R17 with a 235/50ZR15?

Yes, you can indeed use size 235/50R17 on the 2012 Chevrolet Volt.

The largest that we've fit on this vehicle is the factory 225/50R16, sorry.
