What is the tire model for Audi A4?
4 Answers
Audi A4 tire models include 225/50r17 and 245/40r18. The Audi A4 is a sedan under FAW-Volkswagen, with exterior dimensions of 4737mm in length, 1842mm in width, and 1428mm in height. It has a trunk capacity of 505 liters and a fuel tank capacity of 54 liters. The Audi A4 is equipped with a 2.0-liter turbocharged engine and a dual-clutch transmission, delivering a maximum power of 140 kW at 6000 rpm and a maximum torque of 320 Nm. It features a five-link independent front and rear suspension, tire pressure monitoring system, and a rearview camera.
I've been driving an Audi A4 for several years and have given a lot of thought to tire specifications. The A4 varies significantly across different years and trim levels. My 2018 Sport model uses Michelin Primacy tires in size 245/40 R18, while the base model might come with 225/50 R17 Goodyear tires. For daily driving, the 245mm width provides better cornering stability but consumes slightly more fuel. The narrower 225mm tires save fuel but offer slightly weaker traction in rain or snow. I recommend checking tire pressure quarterly and maintaining it around 2.4 bar to prevent blowouts or suspension damage. When replacing tires, don't skimp on quality—brands like Bridgestone or Continental offer better durability. The door frame label shows the manufacturer's recommended specifications, so follow that for replacements. For modifications, many people upgrade to 19-inch wheels with wider tires, but this affects ride comfort and should be done cautiously. In short, good tires are the first line of defense for driving safety—don't underestimate their importance.
As a tech-savvy car enthusiast, I find the tire selection for the Audi A4 incredibly fascinating. The original tire specifications, such as 245/40 R18, indicate a width of 245 millimeters, a sidewall height that is 40% of the width, and an 18-inch rim size, which affects handling and shock absorption. The sport version of the A4 often uses these tires for agile handling, while the base model's 225/50 R17 tires lean more towards comfort but offer slightly softer acceleration. When choosing tires, don't just focus on size—consider road conditions: summer tires provide excellent grip in high temperatures, while winter tires ensure stability on snow. The ideal tire pressure is between 2.3-2.6 bar; too low and they wear out quickly, increasing fuel consumption. Check the tread depth—new tires have 8 mm, and if it drops below 3 mm, it's time to replace them. If you're upgrading to 20-inch rims for the A4, remember to adjust the suspension to avoid excessive bumpiness. My personal favorite is the Michelin PS4, which enhances the A4's high-speed stability. During maintenance, use a tire pressure gauge for accuracy to ensure safety.
Brothers looking to upgrade tires for their Audi A4, let me share some insights. The factory tires like 245/40 R18 or 225/50 R17 are just the starting point, but they're too conservative. When I did my modification, I went for 20-inch wheels with 255/35 R20 Pirelli P Zero tires, instantly making it look more aggressive with improved grip. However, increasing the size requires suspension modifications and alignment, otherwise, it can lead to a bumpy ride or damage the chassis. Don’t just choose tires for looks; consider performance: A4’s drivetrain suits wider tires like 245 or 255 mm, as narrower ones can slip in corners. Maintenance tips: adjust tire pressure to around 2.5 bar and check for surface cracks every time you wash the car. Recommended brands are Continental or Dunlop for their anti-slip and durability. After modification, highway driving feels more stable, but fuel consumption slightly increases. Play with tires in moderation, safety first.
