Both the cars are good with equivalent price, features, power and almost same mileage. Also, both the manufacturers have good number of dealerships and cheap replacements parts. Though, Maruti has recently launched the WagonR with automatic transmission that is unavailable with i10. Also, WagonR is available with dual-airbags and ABS options to add to the safety of the car. So, the WagonR clearly has a edge over i10 as it is a safer car with a little difference of price.
Radial tyres are defined as the tyre with reinforcing steel wires running radially, that is, parallel to the direction of motion. While, tubeless tyre is defined as a radial tyre that doesn't has an air holding tube.
As both of them are one and the same tyre there is no difference or comparison between these two. However, there is difference between radial or cross-ply tyres. The former is prevalent with modern cars, while the latter is used in trucks and load bearing vehicles as cross-ply construction gives more support to tyre walls.
Radial tyres are better for passenger vehicle use because they provide a comfortable ride by smoothing-out the road bumps. Radial tyres are usually tubeless.
