Short Term Mixing Tire Types: Dangerous?

[Pooch]

I keep up with reading all the tire threads here but do not recall having come across any discussion of this subject:

2021 RTL

In need of a rear tire VERY soon...within 2000 more miles, per dealer at 9,300 mile oil change.... I am at 10,000 miles now.
Dealer has a Kumho tire he will put on the rear so I guess I am stuck with that since I have no tools nor expertise as to tire changing. He wants close to $300 for the tire and labor.
I thought that pretty high considering the cost of the tire at Tire Rack... anyway, I digress...

Question: If I put the Kumho car tire on the rear while still running the original stock Kenda front tires....will it make the handling "wonky" or dangerous to have a mix of rubber like this?

I intend to change the front Kendas out later this spring as they still have fairly decent mileage left in them, per the dealer, but this month is a heavy hitter for me for general necessity expenses (house insurance, car insurance, dental expense, etc) so I need to wait a bit to purchase the fronts... but still will be riding and riding.. it just makes me nervous to think about pushing that original rear tire with its current mileage, and it makes me nervous if mixing the tires will make the handling dangerous or totally uncomfortable.

Thanks in advance for your advice.

Answer: No it will not

and when this exact question was asked 10 years ago ( and at least on 20 more occasions ) I said the same thing ...... Mike

Because the stock back tires are so bad, I would think every spyder out there has done this.

I had a Kumho installed at Coyote Powersports, which I assume you are referencing, last May. Total cost was $355.00, and it appears that if you were quoted "close to $300.00", you would be getting a better deal than I got. In answer to your question regarding not changing the front Kendas, I didn't do that at the time I got the rear put on, as they would not install front tires that I would have purchased and brought to them. I didn't notice any big change in handling by not changing the fronts at that time. The dealer that I use here in Austin, Ride now Austin, installed the front tires I bought at Tire Rack, Vredestein Quatrac 175/55R15 that cost me $246.12 tax included. They charged me $165.00 to R&R the front tires. There now is a marked difference in handling for the better. I, like you, don't have the tools or expertise to change tires, so I was stuck with shelling out north of $750.00 all in, so I just sucked it up and did it. I'm sure others here have done or had it done for less, but there it is. Good luck.u

I have been doing some tire mixing since day one. The fronts always outlast the rears. For me usually by 5K or more miles. I currently have one with three Kenda K9's on it and the second with the original OEM Kenda's on it.

Yes it was Coyote. Since the rear tire is so involved as to change I thought I would let Rocky do that one as he is very good and knows the intricacies of the Spyder … but am thinking of letting Destination Power Sports here in Kerrville change the fronts in a month or so since they are basically pop on/off and they said they would put on any tire I wanted.

You could always buy the fronts you want and take them, along with the wheels, to Discount Tires and have them put on the fronts. You can pull the front tires in 10 minutes or less.

You will be fine. This is what most do. If you're lucky enough to have a decent set of OEM tires on front. You might as well wear them out before you go to car tires.

( mostly ) ..... If you have a pair of Kenda's that aren't defective (ie. round, balanced, and not cupping yet ) I have always said keep them until they wear out, then get some auto tires put on ..... Mike

...As others have said, 'NO PROBLEM'.
Just don't make it a problem by not installing better
Tires in the future.

It's fine as stated.
I just installed a Kumho on the rear of mine. 99 for the rubber, 32 for mount, 9 for balance beads and screened tire valve.
Local tire place was able to mount with no problem.
I run Kenda car tires, Komet Plus KR23A, up front.

I had a Kumho rear on my F3T and found it to be a more comfortable ride than the Vred that I replaced it with. I think the Kumho has softer sidewalls. Bear in mine that I'm an easy rider and rarely get caught in the rain. I've got a new '22 coming when the brake spring gets replaced and when I wear out the OEM, it will be replaced with a Kumho.

Seat of the pants isn't the best way to tell anything ..... What was sidewall rating for that Vredestein & what is the sidewall rating for the Kumho ..... The higher the weight rating the stiffer the sidewall ..... JMHO .... Mike
