Tire Combo mixture..
245/40/18 front Toyo T1
295/30/19 rear. Toyo R888
or any other brand of tire but different sizes as above.
If so do you have any problems with this mixture?
Does anyone have any suggestions as to what size to run up front?
Thanks...

Thats not a very good thing to do, my friend. Even worse would be to mix manufactures brands....
A brand designation (model of a tire) is constructed/engineered to compliment traction, handling, and braking dynamics on the particular vehicle that runs that size designation.
By mixing the "models"...you risk conditions such as oversteer/understeer, premature loss of wet traction in either the front or rear, throwing the traction control system off.... loss of cornering stability from either the front or rear due to tread surface rollover protection that may be slightly inferior in one of the models.... loss of grip in tight maneuvers due to the design of the tread blocks which reduce/or increase tread flexing....
Can it be done? yes.....but not by the average enthusiast.. profession automotive racing engineers and profession drivers who have different styles and need a "tailoring" sitiuation with their front/rear tires experiment with different combos until they come up with the right one.
Personally, I would stick with the same brand designation on all four corners for the best overall performance from the car.

So the best would be go with Toyo R888 front and rear even though the fronts are Toyo but not R888s?
