I've been trying to find a 33x9.50R15 for a while. This size is listed in the attached brochure. I've been looking online for these but have not been able to find any. I called Kenda today and spoke with a rep who told me this size was currently being sent to their distributors and should be available at the retail level in 6-8 weeks. Just thought I'd pass this along for those who are possibly looking for a taller and slightly thinner profile tire for their 40.
