I am on my second set of Toyo T1R 195/45-15 tires. Great grip. Only last about 25,000 miles, but that is 5 years for me.
With the 15" wheels do you need to modify the fenders? and for the widths mentioned do you need fender flares?
Tirerack never has carried Toyo T1R in this size. I have gotten them from tire easy (out of stck) and https://www.discountedwheelwarehous...ROXES+T1R+195/45R15+WW+78V&partno=Toyo-250760Hi Todd,
I had seen your recommendation in old threads on the subject. Tirerack doesn't even list 195/45/15 as a possibility today. A few weeks back, they had the Toyos and Federals listed and I was going to order the Toyos from them. Walmart still lists the Toyos and Federals, so maybe I will try ordering and see what happens. Tireeasy has the Federals and a few choices all season tires. This will likely become the same quest we had with 185/60/13.

As other have said, it depends on several factors. In addition to the ones already noted, another factor is the front suspension track rod (otherwise known as torque strut, brake rod, trailing arm, radius arm, and other names). Perhaps more specifically the bushings on the leading end of that rod. They determine the exact location of the rod's pivot point, which directly affects caster. However it also affects the physical location of the front wheel within the fender arch. If you stand back and look at it you'll notice the X's front tires don't sit in the center (front to back) of the opening. They are more toward the front of the car. This often causes wide tires to hit the lowest point of the leading edge of the fender (bottom front corner) when the steering is turned toward full lock. So depending on all of the factors involved, this seems to be one of the most common areas where some clearencing is required.With the 15" wheels do you need to modify the fenders?
I have a set of wheels/tires that are designed for FWD applications, so the offset is totally wrong for the X. Therefore I had custom spacers (adaptors for the 4x100 pattern) made to locate them correctly for my setup. They are 6" wide x 15" diameter, with 195/50 tires mounted. For the most part they fit, with the exception I just noted in my last post - the lower front corner of the fender opening. But I also have coilovers and unknown final offset, so this size tire may not work for most X's. I'm also still building the car, so I may find they rub under certain driving conditions once everything is finished. The tires came on the wheels and need to be replaced anyway, but I'll wait to see how they clear before buying new ones. I'm not concerned with the overall circumference; to me the bigger rolling length will help the short final drive on the X.Generally the largest is a 185/45 15 tire on a 6” wide 15” diameter wheel with a positive offset of around 20-25.
