987 Tire Questions, inregards to 19s


Recommended Posts

What is the max width that I can put in the front and rear of a 987 Boxster considering that the wheels are 19s and there are no suspension modifications. I'm thinking about running 285/35/19 in the rears, is that too wide? What do you guys think about the Toyo T1Rs?

The actual width isn' the main issue , its getting the track width , offset and rolling radius correct. Stock wheels are 235/35/19 and 265/35/19, so you need to look at a site like tyrebibles.com to get an equivalent rolling radius for the larger width you are planning. Looking at aftermarket tuners like Techart I' suggest a 295 is probably the widest you want to go with a spacer on the rear. Wider tyres on the front won't give you much in grip or handling , so better just to put spacers on that axle and keep a similar size to OEM. Personally I'd look at techart and speedart and copy their wheel size and spacer settings. They are German companies so they must fit wheels and tyres that are approved by the TUV as being safe and approved as aftermarket items.
