can i get some help here

without buying any new wheels for a car. How can I find out the largest size wheel and tire i can put on????? Sorry if this has already been asked.

Go to a tire shop they can usually tell you right away.

yea i figured that one but i was just wondering if there was something i could do on my own, i like doing things once or twice just so i know how something is done for future reference...thanks though.

Adding inches to the wheel diameter for wider, low aspect ratio tires can increase your car’s handling capabilities.

Plus Zero
Increase the section width and lower the aspect ratio while retaining the wheel diameter. This replacement tire increases the contact area and lowers the tread profile for improved traction and quicker response.

Plus One
This sizing mounts tires with an increased section width and a lower aspect ratio on wheels of a wider diameter. A Plus One fitment for a car with 14-inch original equipment wheels would use 15-inch wheels.

As a general rule of thumb, Plus One Sizing:
Increases section width by 10 mm.
Decreases aspect ratio by 10 points.
Increases rim diameter by 1 inch.

Plus Two
Increased wheel widths in plus sizing also contribute to greater tire stability, and improved cornering and maneuverability. A Plus Two fitment for a car with 13-inch original equipment wheels would use 15-inch wheels.

As a general rule of thumb, Plus Two Sizing:
Increases section width by 20 mm.
Decreases aspect ratio by 20 points.
Increases rim diameter by 2 inch.

Plus sizing can effect your abs sensors. Dealers have additional information for Plus Sizing ABS-equipped vehicles.
