Mastering Upsizing Wheels and Tires: Your Ultimate Plus Sizing Guide

Discover the art of wheel and tire plus sizing with our ultimate guide. Learn the ins and outs of upgrading your ride for better handling, braking, and style, while navigating potential drawbacks. Tailor your choices perfectly with practical advice and step-by-step assistance for a flawless upgrade.

What is Plus Sizing?

Let’s kick things off with plus sizing – it’s kind of like giving your car a pair of snazzy running shoes that not only look great but boost performance to boot. Simply put, plus sizing is when you up the ante on your wheel diameter without messing too much with the overall tire diameter. You get the visual punch of larger rims without the side effects of a significant change in tire size.

Imagine you’re cruising down the road, and your ride feels more responsive; that’s likely due to the stiffer sidewalls and increased contact patch with the road you get with plus sizing. Your car reacts better, brakes cleaner, and let’s be real – it turns heads with its newfound road stature.

But let’s not sugarcoat it – you need to be a bit like Goldilocks when choosing the size that’s “just right” for your vehicle. Go too big, and you’re talking fitment woes, like your tire playing an uncomfortable game of rub-a-dub-dub with your wheel wells. Not to mention, a ride harsh enough to make you feel every pebble on the road. It’s a balancing act where rewards in aesthetics and agility come with a dash of caution.

Measuring Tire Size

Let’s decode that tire size scribble on your sidewall, shall we? That mysterious mix of numbers and letters actually speaks volumes about your tire, you just need the secret decoder. It’s all about three things: section width (how wide your tire is), aspect ratio (sidewall height compared to its width), and wheel diameter (the size of your wheel).

Handy-dandy online tire calculators are like treasure maps to the right tire size. Plug in your numbers, and voilà, you know your tire dimensions. They let you play with sizes side by side, so you can see the impact on your ride before you part with any cash.

Your main aim is to keep the tire diameter in the same ballpark as the original equipment manufacturer’s (OEM) specs. A little wiggle room on width and aspect ratio won’t ruffle too many feathers, but pushing the envelope too far might have your vehicle scolding you for being inconsiderate.

Plus Sizing Examples

Picture this—your OEM tire says 205/55R16, and you’re eyeing a plus 1 setup. This means you’re hopping up to, say, a 225/45R17 – you’ve increased your wheel diameter by an inch but managed to keep the total diameter of your wheel-tire package consistent, minimizing disturbances in the force of your vehicle’s harmonious existence.

Let’s play dress up with your wheels. Plus 2, plus 3? It’s all a fun game until you find out you need a lift kit. Pictures paint a thousand words, so checking out photos can save you from a thousand mistakes, showing the scale of change with each increment.

Plus Sizing Pros and Cons

Adding inches to your wheels isn’t just about looking good—it rewrites the rules of your car’s grip and handling, sharpening turns and bringing you to a standstill more urgently when you hit the brakes. It’s like your car’s saying “I got this” as it hugs the curves and stops on a dime.

On the flip side, those bigger wheels can be chatterboxes, narrating every twist and turn of the road directly into your seat. Comfort can take a backseat, especially with ultra-low-profile tires. Not to mention, that swanky wheel assembly adds weight, which can influence everything from your speedometer to how hard your engine works.

Choosing the Right Plus Size

Choosing the Cinderella tire for your car’s proverbial glass slipper is more science than fairy tale. Take into account your vehicle’s personality, wheel specification, and how you plan to strut your stuff on the street or off-road.

If you dream of monster tires, you’ll likely need a lift kit to house those big boys safely. You’ll also need to size up your brakes to ensure they’ll fit snugly inside the rim. And, to avoid the dreaded scrubbing action against your fender, make sure to do the wiggle test – a little dance between your tires and chassis that ensures they won’t touch.

Preserving the overall diameter within a 5% margin is the sweet spot, and please don’t forget about offset and backspacing—this is not the time for your wheels to be socially awkward. And hey, we all like a hard worker, but your beauty’s backbone, its load-carrying capacity, is a spec not to skimp on.

Installing Plus Size Wheels & Tires

Now, let’s talk about installation – like a pit stop, but for plus sizing. Start by waving goodbye to your current wheels and tires. Give your brakes and suspension a once-over—no one likes unexpected guests during renovations.

Before things get serious and the tires make their bond with the wheels for good, court them a bit; match them up and make sure they’re compatible. Once confirmed, marry those tires to those rims like a love story of the century.

Torquing your lug nuts to spec is like that final spell check before you submit an important paper—vital. Make sure everything else is in its place, no wheel-to-vehicle component heartaches, please. And after a test drive that sings, swing by your mechanic’s for a quick check. After all, with great power (and size) comes great responsibility.

Get that alignment done to stay true on your path, because as with life, your vehicle also seeks balance with its new size. With all said and done, sit back and enjoy the ride! If your car could talk, it’d probably thank you. And now, what are your thoughts? Did you go plus size and find it to be a game-changer? Share your experiences below. Maybe your journey can illuminate the path for someone else’s upgrade adventure.
