Project E39 M5: Yokohama Advan GT Wheels & Nitto Invo Tires
By Martin Gonzales
After installing the StopTech Trophy Brake System on our Project BMW E39 M5 we unfortunately, or fortunately depending on how you look at it, had to say goodbye to our stock wheel package. The OE mesh wheels were not designed to clear huge multi piston calipers and neither the front or rear wheels would clear our new brake kit. So we had no other choice but to do a long-needed upgrade to our project’s wheels and tire package.
If you’ve been following our M5 project, you’ll recall that when we installed the front and rear Trophy kit on our M5 we weighed all the components and found our new brake system came with a 6 pound weight penalty per rear corner. This meant our new wheel and tire combo would have to meet a few requirements. Not only did we need a wheel that could clear the large StopTech calipers and help us improve on our unsprung weight gain, we also needed the wheel to be wider than stock as we were looking to increase the M5’s contact patch in preparation for future horsepower mods.
Our requirements for tires would be no less demanding. Though our E39 M5 is a high performance vehicle, it is not a race car. So we wanted a tire with enough grip that it could be pushed through the canyons with confidence, but that was still civil enough to drive on a Sunday cruise comfortably.
Enter Yokohama Wheels and Nitto Tire!
The Invo has a much more aggressive tread pattern than Nitto’s NT05 max performance summer tire, which helps it evacuate water from the zone between the tread and road for better wet grip. The Invo is engineered to have a decent ride and has by nature a softer sidewall than the reinforced sidewall and bead filled ultra high-performance Nitto NT05. The ride is designed to be noticeably better than the NT05, but by no means is the Invo a sloppy or sluggishly responding tire. The Invo is also available in larger diameter and lower profile plus fitments than the NT555 G2s we were already running on our stock E39 M5 wheels.
